Find the change in gravitational potential energy

Reference no: EM13242687

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?

(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?
