How high is the rock above the ground

Reference no: EM13710537

Solve the following questions:

Question I: If the gravitational potential energy of a 35.0 kg rock is 500 J relative to a value of zero on the ground, how high is the rock above the ground?

Question II: If the rock were lifted to twice its original height, how would the value of its gravitational potential energy change?

Please help, completely confused!! Give steps if possible.
