Click on the crate to bring it to a stop, then replace it with the refrigerator. Use the slider to apply a force of about 400 N. After 2 s have elapsed in the simulation, decrease the Applied Force (force exerted) slowly back to zero. Try to do this adjustment in roughly 2 s . While the Applied Force (force exerted) is decreasing, the velocity is:______.
a. constant.
b. increasing.
c. decreasing.

Answer:

While the Applied Force (force exerted) is decreasing, the velocity is decreasing

Explanation:

From Newton's second law of motion, which states that the rate of change of linear momentum is directly proportional to the applied force, and takes place in the direction of the applied force.

Momentum (P) = MV

Thus, F ∝ MV/t

where;

F is the applied force

M is the mass of the object

V is the velocity of the object

From the equation above, force is directly proportional to the velocity of the refrigerator (F∝V). That is, as the applied force is decreasing, the velocity is decreasing and vice versa.

Therefore, while the Applied Force (force exerted) is decreasing, the velocity is decreasing.
