A large metal ball is at rest and a small rubber ball is moving at a high velocity. When they collide the momentum of the small ball decreases. What happens to the momentum of the large metal ball

1 answer

According to the law of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision. In this scenario, the small rubber ball has a higher velocity and momentum compared to the large metal ball before the collision.

Since the momentum of the small ball decreases, the total momentum after the collision must also decrease to satisfy the conservation of momentum. Therefore, the momentum of the large metal ball after the collision also decreases.
