Compute the each part of given question:
Question: A 0.19-kg stone is held 1.4 m above the top edge of water well and then dropped into it. The well has a depth of 5.1 m.
Part I: Taking y = 0 at the top edge of the well, what is the gravitational potential energy of the stone Earth system before the stone is released?
Part II: Taking y = 0 at the top edge of the well, what is the gravitational potential energy of the stone Earth system when it reaches the bottom of the well?
Part III: What is the change in gravitational potential energy of the system from release to reaching the bottom of the well?
