None of the answers correctly describes the situation. 5. Neither exerts a force on the other; the

Answer 1

Answer:

Only 3 is true: The truck exerts the same amount of force on the car as the car exerts on the truck.

Explanation:

Compare the forces if the light truck is standing still when the car hits it.

1. The car exerts a greater amount of force on the truck than the truck exerts on the car. FALSE. This violates Newton 3rd Law of Action-Reaction.

2. The truck exerts a greater amount of force on the car than the car exerts on the truck. FALSE. This violates Newton 3rd Law of Action-Reaction.

3. The truck exerts the same amount of force on the car as the car exerts on the truck. TRUE. This is Newton 3rd Law of Action-Reaction. When there is a contact between objects, both exert on the other an equal and opposite force.

4. None of the answers correctly describes the situation. FALSE. 4 is true.

5. Neither exerts a force on the other. FALSE. If the car hits it then forces must come into play.
