An automobile of mass 1500 kg moving at 25 m/s collides with a truck of mass 4500 kg at rest. The bumpers of the two vehicles lock together during the crash.Compare the force exerted by the car on the truck with that exerted by the truck on the car during the collision. Is on force larger than the other or are they equal in magnitude to each other?What is the final velocity of the car and truck just after the collision.Now this time the car and the truck bounce off each other completely elastically.Compare the force exerted by the car on the truck with that exerted by the truck on the car during the collision. Is one force larger than the other or are they equal in magnitude?What are the final velocities of the car and truck just after the collision?

A large truck breaks down out on the road and receives a push back to town by a small compact car.

Pick one of the choices A through F below which correctly describes the forces that the car exerts on the truck and the truck exerts on the car for each of the questions. You may use an answer more than once or not at all.

1. While the car, still pushing the truck, is speeding up to get up to cruising speed:

A. The force exerted by the car pushing against the truck is equal to that exerted by the truck pushing back against the car.

B. The force exerted by the car pushing against the truck is less than that exerted by the truck pushing back against the car.

C. The force exerted by the car pushing against the truck is greater than that exerted by the truck pushing back against the car.

D. The car's engine is running so it exerts a force as it pushes against the truck, but the truck's engine isn't running so it can't exert a force back against the car.

E. Neither the car nor the truck exert any force on each other. The truck is pushed forward simply because it is in the way of the car.

F. None of these descriptions is correct.

2. If the car and truck are moving at cruising speed, which choice(s) below are true?

A. the amount of force with which the car pushes on the truck is equal to that with which the truck pushes back on the car.

B. the amount of force with which the car pushes on the truck is smaller than that with which the truck pushes back on the car.

C. the amount of force with which the car pushes on the truck is greater than that with which the truck pushes back on the car.

D. the car's engine is running so the car pushes against the truck, but the truck's engine is not running so the truck cannot push back against the car. The truck is pushed forward simply because it is in the way of the car.

E. neither the car nor the truck exert any force on the other. The truck is pushed forward simply because it is in the way of the car.Ā 

A truck does 3.2 kJ of work pulling horizontally on a car to move it 1.8 m horizontally in the direction of the force.Calculate the magnitude of the force.
