Choose the best answer in the previous Question (# 9) but now assume that you push both the car and the truck for the same distancewith the same force. [Hint: See also Chapter 6.]

The person applies the same amount of force on both vehicles, and they travel the same distance. Thus, the work done on both vehicles should be the same.

The work done on both vehicles should be the same as the same amount of force is applied for the same distance traveled.

From the work-energy theorem, you know that this work done will be equal to the change in kinetic energy. As the initial kinetic energy is zero for both car and truck, the final kinetic energy for both will be equal to the work done.

Thus, the kinetic energies of both vehicles are the same.

If the vehicles travel the same distance on the application of the same amount of force, the force on the lighter vehicle (car) must be applied for a smaller interval of time.

Therefore, the car will experience less impulse as it is the product of force and duration of time.

You know that impulse is equal to the change in momentum of a body. As the initial momentum of the vehicles is zero, the car will have less final momentum than the truck.

Thus, the truck has greater momentum.

Therefore, both vehicles have the same kinetic energy, but the truck's momentum is greater. Hence, option (e) is correct.
