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 equal to that of the rock, in the opposite direction.
Explanation: in the collision (an internal interaction) momentum is conserved, so the car's impulse equals the rock's impulse with opposite sign; the car's velocity change is much smaller because its mass is much larger.
