Question

1. a large metal ball is at rest, and a small rubber ball is moving at a high velocity. when they collide, the large metal ball begins to roll slowly. what must have happened to the momentum of the small rubber ball? (1 point) it must have increased it must have decreased it must have become zero it must have stayed the same

Explanation:

According to the law of conservation of momentum, the total momentum of an isolated system remains constant. Initially, the large metal ball has zero momentum (as it is at rest), and the small rubber ball has a non - zero momentum. After the collision, the large metal ball has some momentum (since it is rolling slowly). So, the momentum of the small rubber ball must have decreased so that the total momentum (momentum of metal ball + momentum of rubber ball) after the collision is equal to the initial momentum (which was just the momentum of the rubber ball before collision).

Answer:

it must have decreased
