A beach ball and a bowling ball were sitting on a shelf. Someone bumped the shelf and the bowling ball and beach ball rolled off
the shelf at the same time. They both hit the ground at the same
time and had the same speed.
Which of these statements correctly compares the kinetic energy
of the two objects just before they hit the ground?
A The bowling ball had more kinetic energy because it
had less potential energy when it was on the shelf.
B The bowling ball had more kinetic energy because it
has more mass.
C Both balls had the same kinetic energy because they
had the same speed.
D Both balls had the same kinetic energy because they had the same potential energy when they were on the
shelf.
