Chapter 7 - Linear Momentum - Misconceptual Questions: 6

Answer

Choice A.

Work Step by Step

The moral is not to ignore the vector nature of momentum and impulse. The beanbag and golf ball each have the same momentum just before they contact the ground. The change in momentum of the golf ball is greater when it rebounds, compared to the beanbag’s change in momentum, which is simply brought to a dead stop. The golf ball was not only brought to rest, but the greater impulse reversed its momentum and sent it back the way it came.
