A 0.19-kg stone is held 1.2 m above the top edge of a water well and then dropped into it. The well has a depth of 5.6 m.
(a) 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? (No Response)
J
(b) 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? (No Response)
J
(c) What is the change in gravitational potential energy of the system from release to reaching the bottom of the well? (No Response)
