A 019-kg stone is held 14 m above the top edge of a water


A 0.19-kg stone is held 1.4 m above the top edge of a water well and then dropped into it. The well has a depth of 4.7 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?

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?

J

(c) What is the change in gravitational potential energy of the system from release to reaching the bottom of the well?

J
