A small rock bounces off the windshield of a moving car and experiences a large change in velocity. How does the car’s momentum change?(1 point) Responses It has a change in momentum greater than that of the rock, in the opposite direction. It has a change in momentum greater 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 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 does not change.

Answer 1

The correct response is: It has a change in momentum equal to that of the rock, in the opposite direction.

According to the law of conservation of momentum, when two objects interact (in this case, the rock and the car), the total momentum before and after the interaction must remain the same. The change in momentum of the car will be equal in magnitude but opposite in direction to the change in momentum of the rock.
