Responses
It does not change.
It does not change.
It has a much smaller change in momentum than that of the rock, in the opposite direction.

The correct response is:
**It has a change in momentum equal to that of the rock, in the opposite direction.**
This is a consequence of the law of conservation of momentum. When the rock bounces off the windshield, both the rock and the car exert forces on each other due to Newton's third law (for every action, there is an equal and opposite reaction). Thus, the change in momentum of the rock is equal in magnitude but opposite in direction to the change in momentum of the car.
