A 3 kilogram cat is resting on top of a bookshelf that is 1 meters high. What is the cat's gravitational potential energy relative to the floor?

We have: Gravitational Potential Energy (U) = mgh

Here, m = 3 Kg

g = 9.8 m/s² [ constant value for earth system ]

h = 3 m

Substitute their values into the expression:

U = 3 * 9.8 * 3

U = 88.2 J

In short, Your Answer would be 88.2 Joules
