Consider a box sitting atop a frictionless inclined plane.

If the box is pushed off the edge of the inclined plane, it falls vertically to the ground under the influence of gravity only. If the box is released from rest in the other direction it slides down the frictionless inclined plane. The inclined plane has a height, $h$, and a length, $l$. Which of the following results in the box having the greatest velocity just before striking the ground?

A

The box sliding down the inclined plane will have the greatest velocity just before striking the ground.

B

The box falling vertically off the edge will have the greatest velocity just before striking the ground.

C

Regardless of which way the box falls/slides, it will have the same velocity just before striking the ground.

D
