a large truck collides head-on with a small compact car. during the collision:

1. A large truck collides head-on with a small compact car. During the collision: the

truck exerts the same amount of force on the car as the car exerts on the truck.
neither exerts a force on the other, the car gets smashed simply because it gets in the way of the truck.
the truck exerts a force on the care but the car does not exert a force on the truck.
the truck exerts a greater amount of force on the car than the car exerts on the truck.
the car exerts a greater amount of force on the truck than the truck exerts on the car.

2. Two metal balls are the same size, but one weighs twice as much as the other. The balls are dropped from the roof of a single-story building at the same instant of time. The time it takes the balls to reach the ground below will be:

about half as long for the lighter ball.
about the same time for both balls.
considerably less for the heavier ball, but not necessarily half as long.
about half as long for the heavier ball.
considerably less for the lighter ball, but not necessarily half as long.

B. The truck exerts more force on the mosquito than the mosquito exerts on the truck.

C. The mosquito exerts the same force on the truck as the truck exerts on the mosquito.

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
