Question

What is the gravitational potential energy of a `9 kg` object on a shelf `3/5 m` high?

Answer 1

`GPE ~= 53 J`

Explanation:

The formula for Gravitational Potential Energy is `GPE = m*g*h`.

Plugging in your data

`GPE = 9 kg*9.8 m/s^2*3/5 m = 52.9 kg*m^2/s^2 = 52.9 J ~= 53 J`

I hope this helps,
