Explanation:
At what point does a rubber band have the most elastic potential energy? Explain.
Answer:
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. ... When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.

A car is travelling to the right with a speed of 40 m/s when the driver slams on the brakes. The car skids for 4 s with constant acceleration before it comes to a stop. What was the rate of the car's acceleration as it skidded to a stop?
Answer:
10m/s^2
Explanation:
Given data
velocity= 40m/s
time= 4 seconds
Acceleration a =????
We know that
a= velocity/time
substitute
a=40/4
a= 10m/s^2
Hence the acceleration will be 10m/s^2
A 2.0-kilogram mass is moving with a speed of 3.0 m/s. What is the kinetic energy of the mass?
Answer: 9 Joules
Explanation:
Kinetic enegry is one half the mass multiplied by the velocity squared
KE = 1/2mv^2
[tex]KE=1/2(2)(3^2)\\KE=3^2\\KE=9J[/tex]
The kinetic energy of the body is 9J
What is kinetic energy?Kinetic energy is the energy possessed by a body due to its motion.
It is claculated by formula,
K.E = [tex]\frac{1}{2}mv^{2}[/tex]
Here,
The mass of the body = 2.0kg
speed = 3.0m/s
So kinetic energy K.E = [tex]\frac{1}{2}mv^{2}[/tex]
K.E = [tex]\frac{1}{2} (2)3^{2}[/tex] = 9J
So the kinetic energy of the body is 9J

A. 0.2 kg
B. 616 kg
C. 43 kg
D. 102 kg
Answer:
43 kg
Explanation:
Force (F) = 162 N
acceleration (a) = 3.8 m/s²
mass (m) = ?
We know
F = m * a
162 = m * 3.8
m = 162 / 3.8
m = 43 kg
It's mass is 43 kg.

What is the relationship between the mass of the objects and the force exerted?
Answer:
Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects, and is inversely proportional to the square of the distance between them. The factors G, M, and r are the same for all masses at the surface of the Earth.

A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass?
A. 575 kg
B. 3.8 x 104 kg
C. 0.15 kg
D. 6.7 kg
Answer:
We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
Explanation:
Given
Force F = 500 NAcceleration a = 75 m/s²To determine
Mass m = ?
Important Tip:
The mass of a rock can be found using the formula F = ma
Using the formula
[tex]F = ma[/tex]
where
F is the force (N) m is the mass (kg) a is the acceleration (m/s²)now substituting F = 500, and a = 75 m/s² in the formula
[tex]F = ma[/tex]
[tex]500 = m(75)[/tex]
switch sides
[tex]m\left(75\right)=500[/tex]
Divide both sides by 75
[tex]\frac{m\cdot \:75}{75}=\frac{500}{75}[/tex]
simplify
[tex]m=\frac{20}{3}[/tex]
[tex]m=6.7[/tex] kg
Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.

Answer:
it would be 3
Explanation:
because you have to divide the length by the height of the incline.
The mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.
What is the mechanical advantage?Mechanical advantage is a measure of the ratio of output force to input force in the system, it is used to obtain the efficiency of a mechanism.
The formula for the mechanical advantage of the inclined plane is found as;
[tex]\rm Mechanical \ advantage = \frac{length}{height} \\\\ Mechanical \ advantage =\frac{9}{3} \\\\ Mechanical \ advantage =3[/tex]

A car moving with an initial velocity of 36 m/s slows down at a constant rate of -2.8 m/s^2 . What distance does the car travel after 3 seconds of deceleration? Remember to include units in your answer! *
Answer:
the distance covered by the car is 95.4 m.
Explanation:
Given;
initial velocity of the car, u = 36 m/s
acceleration of the car, a = -2.8 m/s²
time of motion of the car, t = 3 s
The distance covered by the car is calculated as;
s = ut + ¹/₂at²
s = 36(3) + ¹/₂ x (-2.8)(3)²
s = 108 - 12.6
s = 95.4 m
Therefore, the distance covered by the car is 95.4 m.

you lift a 5 Kg bowling ball with a force of 49 N to a height of 40 m, what is the amount of work done on the
bowling ball to lift it?
Answer:
Workdone = 1960 Joules.
Explanation:
Given the following data;
Mass = 5kg
Force = 49N
Height (distance) = 40m
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 49*40
Workdone = 1960 Joules.
Therefore, the amount of work done on the bowling ball to lift it is 1960 Joules.
