Question

A 1600 kg car moving at 22 m/s is in a wreck with a 2900 truck moving at 32 m/s in the opposite direction. Which exerts a greater magnitude of force on the other?

Answer 1

In the instant of the collision, newton's third law says that each exerts an equal force on the other. Newton's second law, however, says that the acceleration of each is equal to that reaction force divided by the object's mass.
