Newman · Answer 1

c. continues at the velocity it had before the second force was applied.

Explanation:

We know that acceleration is that the rate of change of velocity is known as and when velocity is constant then the acceleration becomes zero. When acceleration is zero then the force on the body is zero and we say that the body is in the equilibrium position.

When the first force applies then due to acceleration the velocity of the object will increase and when the second force applies then the object will move as the velocity is had before. Because when the second force apply then the object comes in the equilibrium position and it will move with constant velocity.

Therefore the answer is C.
