What is the gravitational potential energy of a ball on Mars with aweight of 38.

Question

What is the gravitational potential energy of a ball on Mars with aweight of 38.2 N when it is sitting on a shelf 13.82 m above theMartian floor?

An astronaunt lands on the dwarf planet Eris and decides to performexperiments. One of these experiments is to measure theacceleration due to gravity. He finds that the acceleration due togravity is constant at 0.8 m/s2. Then he finds a deepcrater and wants to know its depth so he fires a rope to the centerof the crater. He then slides down the rope without friction andfinds that his velocity at the bottom is 58.32 ± 0.26m/s. Using this information and the fact that the astronaunt has aweight with his suit of 240 N on Mars, find the average depth ofthe crater.

Explanation / Answer

weight W = 38.2 N
height h = 13.82 m So, the gravitational potential energy of a ball on Mars = W h                                                                                    =527.924 J
