how much time would it take to stop a 2.75kg ball traveling at 3.90m/s if a constant force of -5.00N is applied to it?
Answer: 2.15secs
Explanation:
Force = mass*velocity/time
F = 5N
M = 2.75kg
V = 3.90m/s
5.00 = 2.75*3.90/time
Time = 10.725/5.0 = 2.15sec
It will take approximately 2.145 seconds to stop a 2.75 kg ball traveling at 3.90 m/s with a constant force of -5.00 N.
First, we need to calculate the initial momentum of the ball using the formula:
Momentum (p) = mass (m) × velocity (v)
Given:
mass (m) = 2.75 kg and initial velocity (v) = 3.90 m/sp (momentum) = 2.75 kg × 3.90 m/s
p (momentum) = 10.725 kg·m/s
Next, we use the principle of impulse to find the time needed to stop the ball. Impulse (J) is equal to the change in momentum, and it is also equal to the applied force (F) times the time (t):
Impulse (J) = Force (F) × time (t)Since the force applied is -5.00 N (acting against the ball's motion), we rearrange the equation to solve for time:
t = J / FThe change in momentum is equal to the initial momentum (since the final momentum will be 0 when the ball stops):
J = 10.725 kg·m/sThus,
[tex]t = \frac{10.725 kg \cdot m/s}{ 5.00 N }= 2.145 s[/tex]Therefore, it will take approximately 2.145 seconds to stop the ball.

When a beam of light passes from substance 1 (index of refraction = 1.55) to substance 2, it has an angle of incidence of 39 ∘
and an angle of refraction of 24∘ What’s the index of refraction of substance 2? For those who’ll attempt the problem, Snells law should be used.k
Answer:
2.40
Explanation:
Snell's law states:
n₁ sin θ₁ = n₂ sin θ₂
where n₁ and n₂ are the indexes of refraction, θ₁ is the angle of incidence (relative to the normal), and θ₂ is the angle of refraction (relative to the normal).
1.55 sin 39° = n sin 24°
n = 2.40
Three forces act on an object (at the origin of a rectangular coordinate system). Force one, F1, has a magnitude of 5.81 N and a direction Theta1 = 77.0 degrees, force two, F2, has a magnitude of 4.88 N and a direction of Theta2, = 156 degrees, and a force three F3, has a magnitude of 4.52 N and a direction of Theta 3 = 289 degrees. add these three vectors using the component method of vector addition. Call the resultant vector F and write the answer in component form (ie using unit vectors). then calculate the magnitude and direction of the vector F.
Answer:
F = -1.682 i + 3.374 j [N] ; F = 3.77[N]; α = 65.78°
Explanation:
In order to be able to understand this problem more easily, we will have to draw the vectors at the point of origin and in this way, with the help of the angles we will be able to find each of the components of the forces.
Looking at the attached image we can see each of the three forces, take each force and decompose them into the x & y axes.
F1 = 5.81 [N]
[tex]F_{1x} = 5.81*cos(77) = 1.306[N]\\F_{1y} = 5.81*sin(77) = 5.66[N][/tex]
F2= 4.88 [N]
[tex]F_{2x}= - 4.88*cos(180-156) =-4.458[N]\\F_{2y}= 4.88*sin(180-156) =1.984[N][/tex]
F3= 4.52 [N]
[tex]F_{3x} = 4.52*cos(360-289)=1.47[N]\\F_{3y} = - 4.52*sin(360-289) = -4.27[N][/tex]
Now we can sum each of the forces in the different components
[tex]F_{x} =F_{x1}+F_{x2}+F_{x3} = 1.306-4.458+1.47 = - 1.682[N]\\F_{y} =F_{y1}+F_{y2}+F_{y3} = 5.66+1.984-4.27 = 3.374[N][/tex]
F = -1.682 i + 3.374 j [N]
The total magnitude can be calculated by Pythagoras theorem
[tex]F = \sqrt{(1.682)^{2}+(3.374)^{2} } \\F = 3.77 [N][/tex]
The direction can be calculates as follows:
tan(α) = 3.374/1.682
α = 65.78°
This angle was calculated with respect to the horizontal

Answer:
Acceleration = 3.5 [m/s^2]
Explanation:
We can solve this problem using Newton's second law, which states that the sum of forces on a body is equal to the product of the mass by the acceleration
F = 350 [N]
m = 100 [kg]
Using Newton's second law we have:
F = m*a
where:
F = force [N]
a = acceleration or desacceleration [m/s^2]
therefore:
a = 350/100
a = 3.5 [m/s^2]

Explain using words or visuals how minerals originally found in magma could travel
through the rock cycle and eventually end up in each of the three main classifications
of rocks. Describe what patterns must occur for each rock type to change into another.
Include any surface and sub-surface events that can be a contributing factor to the
rock cycle. SC.7.E.6.2
Answer:
Explanation:
Magma is a molten and semi-molten rock mixture found under the surface of the Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases. When magma is ejected by a volcano or other vent, the material is called lava. Magma that has cooled into a solid is called igneous rock. Magma is extremely hot—between 700° and 1,300° Celsius (1,292° and 2,372° Fahrenheit). This heat makes magma a very fluid and dynamic substance, able to create new landforms and engage physical and chemical transformations in a variety of different environments. How Magma Forms Earth is divided into three general layers. The core is the superheated center, the mantle is the thick, middle layer, and the crust is the top layer on which we live. Magma originates in the lower part of the Earth’s crust and in the upper portion of the mantle.
Molted magma comes outside Earth's surface and formed igneous rocks. Due to natural decay, this igneous rocks forms sedimentary rocks and due to changes of temperature, pressure and chemical changes both of the rocks transforms into metamorphic rocks.
What is rock cycle?A fundamental idea in geology, the rock cycle illustrates how the three primary types of rocks—sedimentary, metamorphic, and igneous—change over the course of geologic time.
When a rock is pushed out of its equilibrium circumstances, it changes. For instance, an igneous rock like basalt may disintegrate and evaporate when exposed to air or melt when it is subducted beneath a continent.
Rocks do not stay in an equilibrium state; rather, they change as they interact with new environments because of the driving forces of the rock cycle, plate tectonics, and the water cycle.

A student fires a cannonball horizontally with a speed of 39m/s from a height of
73m. Neglect drag.
What was the cannonball's initial horizontal speed?
What was the cannonball's initial vertical speed?
How long did the ball remain in the air?
How far from the base of the building will the ball land (measured along the
ground)?
Explanation:
The initial horizontal speed is 39 m/s, and the initial vertical speed is 0 m/s.
v₀ₓ = 39 m/s
v₀ᵧ = 0 m/s
In the y direction:
Δy = 73 m
v₀ᵧ = 0 m/s
aᵧ = 9.8 m/s²
Find: t
Δy = v₀ᵧ t + ½ aᵧt²
73 = 0 + ½ (9.8) t²
t = 3.9 s
In the x direction:
v₀ₓ = 39 m/s
aₓ = 0 m/s²
t = 3.9 s
Find: Δx
Δx = v₀ₓ t + ½ aₓt²
Δx = (39) (3.9) + 0
Δx = 150 m
The initial horizontal speed of the cannonball is 39 m/s, its initial vertical speed is 0 m/s, it remained in the air for approximately 3.86 seconds, and it landed about 150.3 meters from the base of the building.
Explanation:The cannonball's initial horizontal speed is the speed at which it was fired, which is 39 m/s. Since the cannonball was fired horizontally, its initial vertical speed is 0 m/s.
To find out how long the ball was in the air, we need to use the equation of motion. With the use of the formula for the time of flight for a vertically projected body (t = √(2h/g)), where h is the height from which the cannonball was dropped, and g is the acceleration due to gravity, which is 9.8 m/s², we get t = √(2*73/9.8) = 3.86 seconds.
Finally, to find the distance along the ground, we multiply the time in the air by the horizontal speed (because the horizontal velocity stays consistent in a vacuum), so we get 39 m/s * 3.86 seconds = 150.3 meters.

Answer:
unbalanced force
Explanation:

Two forces acting opposite each other then the acceleration is caused if one force is greater in magnitude than the other.
What is force?A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.
A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). Force is represented by the symbol F (formerly P).
The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time. If the mass of the object is constant, this law implies that the
Acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.
Hence Two forces act opposite each other then the acceleration is caused if one force is greater in magnitude than the other.

Water is made of two hydrogen atoms and one oxygen atom bonded together. Julia is describing how water undergoes a physical change when it boils. She says that the particles shift to be farther apart and that the oxygen and hydrogen separate. She also says that the total mass of the steam is the same as the initial water, and that heat energy was required to cause the change. She finishes her description by saying that the steam can be turned back into water if it is cooled
Boiling water causes molecular movement to increase without breaking H₂O bonds. It's a physical change where molecules move farther apart as steam forms. Cooling steam back into water is reversible, showcasing the unique properties of water's hydrogen bonding.
When water undergoes a physical change, such as boiling, the arrangement of the water molecules changes due to increased kinetic energy. However, the chemical composition remains the same, meaning that the hydrogen and oxygen atoms do not separate into different atoms; they stay bonded as H₂O. The molecules move farther apart, transitioning from a liquid to a gaseous state without changing their actual molecular structure. This transformation requires the input of heat energy, and it is completely reversible; if the steam (water vapor) is cooled, it will condense back into liquid water, demonstrating one of water's unique characteristics due to its ability to form and break hydrogen bonds.
During the boiling of water, the hydrogen bonds between water molecules are broken as they gain enough kinetic energy to escape into the air as steam. When water freezes, however, these molecules form a crystalline structure that is less dense than liquid water, which explains why ice floats. This phenomenon is distinctive to water and differs from most other liquids, where the solid form is denser than the liquid.

6) Acceleration of the plane is 2.87 m/s².
7)Acceleration of the sled is 243 m/s².
Answer:
Explanation:
1) Average acceleration is equal to the rate of change in velocity with respect to time. Here the final and initial velocities are given as 22 m/s and 15 m/s respectively and the time is given as 4 seconds.
So, average acceleration = (Final velocity-Initial velocity)/Time
Average acceleration = (22-15)/4= 1.75 m/s².
Thus, the average acceleration of eagle is 1.75 m/s²
2) Similarly we have to use the above formula for determining the average acceleration of the roller coaster. Here the initial velocity is 4 m/s and final velocity is 22 m/s and the time taken to reach this final speed is 3 seconds.
So, average acceleration = (Final velocity-Initial velocity)/Time
Average acceleration = (22-4)/3= 6 m/s².
Thus, the average acceleration of roller coaster is 6 m/s².
3) Acceleration = 26.8/6.7=4 m/s².
Acceleration in m/s² is 4 m/s².
4) Acceleration required to stop the car = -35.8/2=-17.9 m/s².
Acceleration required to stop the car is -17.9 m/s².
5) Acceleration of the car skidding to stop = (0-22.4)/2.55=-8.78 m/s².
Acceleration required to stop the car is -8.78 m/s².
6) Acceleration of the plane= 88.3/30.8=2.87 m/s².
Acceleration of the plane is 2.87 m/s².
7) Acceleration of the sled = 444/1.83=243 m/s².
Acceleration of the sled is 243 m/s².

r = 8.53 ohm.
Finally the three resistance R1, R2 and the leg resistance which are in parallel connection,
1 / r = (1 / 1.9) + (1 / 2.5) + (1 / 8.53)
= 1.04 ohm
Equivalent resistance R eq = 1 / 1.04 = 0.95 ohm.
The equivalent resistance of the circuit shown in the attachment is 0.958 Ω.
What is a resistor?The resistor can be defined as a device that has some electrical resistance and that is used in an electric circuit for protection, operation, or current control.
Given that there are 6 resistors connected in-between points A and B as shown in the attachment.
R1 = 1.9 Ω, R2 = 2.5 Ω, R3 = 4.4 Ω, R4 = 3.5 Ω, R5 = 5.5 Ω, and R6 = 7.1 Ω.
The resistors R3, R4, and R5 are in parallel connections. Let's consider that R' is the equivalent resistor of this parallel connection, then,
[tex]\dfrac {1}{R'} =\dfrac {1}{R_3} + \dfrac {1}{R_4}+\dfrac {1}{R_5}[/tex]
[tex]\dfrac {1}{R'}= \dfrac {1}{4.4}+ \dfrac {1}{3.5}+\dfrac {1}{5.5}[/tex]
[tex]\dfrac {1}{R'}= 0.69[/tex]
[tex]R' = 1.45[/tex]
The equivalent resistor is in series connection with R6. Hence, the equivalent resistance R'' is given below.
[tex]R'' = R' + R_6[/tex]
[tex]R'' = 1.45 + 7.1[/tex]
[tex]R'' = 8.55[/tex]
Now the resistors R1, R2, and R'' are in parallel connection, so the equivalent resistor R is given as,
[tex]\dfrac {1}{R} = \dfrac {1}{R_1} + \dfrac {1}{R_2} + \dfrac {1}{R''}[/tex]
[tex]\dfrac {1}{R} = \dfrac {1}{1.9} +\dfrac {1}{2.5} +\dfrac {1}{8.55}[/tex]
[tex]\dfrac {1}{R} = 1.043[/tex]
[tex]R = 0.958[/tex]
Hence we can conclude that the equivalent resistance of the circuit shown in the attachment is 0.958 Ω.
