Question

A 2.00 g coin, which has zero potential energy at the surface, is dropped into a 10.0 m well. after the coin comes to a stop in the mud, what is its potential energy with respect to the surface?

Answer 1

When an object falls to the ground under the action of gravity. The numerical value of this acceleration is usually denoted by the symbol g. It will be -mgh - 0.002 x 9.8 x10 = -0.196 J
