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

Jan 4, 2016

I found $571.7 J$

#### Explanation:

With respect to the ground it will be equal to:
$U = m g h$
Where:
$m = 35 k g$ is the mass;
$g = 9.8 \frac{m}{s} ^ 2$ is the acceleration of gravity;
$h = \frac{5}{3} m$ is the height with respect to ground (considered at zero potential energy).
So:
$U = 35 \cdot 9.8 \cdot \frac{5}{3} = 571.7 J$
