Determine the amount of potential energy of a 5-newton book that is moved to three different shelves on a bookcase. the height of each shelf is 1.0 meters, 1.5 meters, and 2.0 meters.

Potential energy is defined as

here we have

mg = weight = 5 N

now for different heights we can say

U = mgh

so potential energy in all three shells will be different and increases with height

im guessing the west of station b
