Question

A ball was positioned in the middle of a smooth ramp and allowed to roll

downward. How does the total mechanical energy of the ball at the bottom of
the ramp compare to its total mechanical energy before it is released?
Assume there is no friction.
A. Its mechanical energy is greater at the bottom of the ramp than
where it started.
B. Its mechanical energy is the same before it was released as it is
when it is rolling off the ramp.
OC. Its mechanical energy could be greater or less at the bottom
depending on how fast the ball is moving.
D. Its mechanical energy is less at the bottom of the ramp than in the
middle of the ramp.

Answer 1

answer A or its mechanical energy is greater at the bottom of the ramp then where it started.
