A 0.375 kg stone is held 1.42 m above the top edge of a water well and then dropped into it. The well has a depth of 4.78 m. Take y = 0 at the top edge of the well.
a) What is the gravitational potential energy of the stone-Earth system before the stone is released?
b) What is the gravitational potential energy of the stone-Earth system when the stone reaches the bottom of the well.
c) What is the change in gravitational potential energy of the system from release to reaching the bottom of the well?
d) Which of these answers would change if you choose a different reference point? Verify your answer by taking y = 0 at the bottom of the well.
*Please answer parts a, b, c, d and explain why you used each of these formulas for the parts please.!!!**
