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.
It has a much smaller change in momentum than that of the rock, in the opposite direction.

It has a change in momentum equal to that of the rock, in the opposite direction.
It has a change in momentum equal to that of the rock, in the opposite direction.

It has a change in momentum greater than that of the rock, in the opposite direction

Answer 1

The correct response is:

It has a change in momentum equal to that of the rock, in the opposite direction.

This reflects the principle of conservation of momentum, which states that in a closed system, the total momentum before and after an event must remain the same. When the rock bounces off the windshield, it experiences a change in momentum, and by Newton's third law of motion, the car experiences an equal and opposite change in momentum.
