A lead ball strikes a wall and falls down, a tennis ball having the same mass and velocity strikes the wall and bounces back. Check the correct statement.

Explanation

The correct answer is that the tennis ball experiences a greater change in momentum than the lead ball. This is because the tennis ball not only comes to a stop when it hits the wall but also bounces back, reversing its direction. The change in momentum is calculated as the final momentum minus the initial momentum. For the tennis ball, this change involves a reversal of velocity, resulting in a greater magnitude of change. In contrast, the lead ball simply comes to rest, leading to a smaller change in momentum. The options suggesting equal changes in momentum or a greater change for the lead ball are incorrect as they overlook the directional component of momentum change.
