Question: Ball A and Ball B have the same mass. Each is dropped from a height of 1 . 0 m onto a platform scale. Ball
Ball A and Ball B have the same mass. Each is dropped from a height of m onto a platform scale. Ball A bounces off the scale, leaving the scale with nearly the same speed it had immediately before contacting the scale. Ball B barely bounces at all, leaving the scale with an almost negligible speed. Both balls are in contact with the scale for the same time interval during the collision. Which of the following correctly identifies which ball, if either, caused the scale the read a larger average force during the collision and provides valid justification?
A Ball A because its momentum changes by a greater amount during the collision.
B Ball A because it gained kinetic energy during the collision.
Neither ball, because both were dropped from the same height and thus had the same momentum before impact.
Neither ball, because both had the same acceleration during the collision.
