Question

A kid slides down an icy (frictionless) hill starting from rest. At the top his gravitational potential energy is 500 J. answer the following about this statement?

His kinetic energy at the top of the hill is

He slides part way down the hill to a point where his gravitational potential energy is 200 J. His kinetic energy at that point will be

He slides all the way down to the valley bottom where his gravitational potential energy becomes zero. His kinetic energy at the bottom will be

Suppose after reaching the bottom he then continues sliding up another icy slope on the other side of the valley. When he finally comes to a stop he will have reached a height

Explanation / Answer

0 300 j 500 j h = 500/mg m is not given
