Question

What is the gravitational potential energy of a `35 kg` object on a shelf `5/3 m` high?

Answer 1

I found `571.7J`

Explanation:

With respect to the ground it will be equal to:
`U=mgh`
Where:
`m=35kg` is the mass;
`g=9.8m/s^2` is the acceleration of gravity;
`h=5/3m` is the height with respect to ground (considered at zero potential energy).
So:
`U=35*9.8*5/3=571.7J`
