# What is the gravitational potential energy of a  29 kg object on a shelf  5/6 m  high?

Dec 30, 2015

237.075 Joules

#### Explanation:

The gravitational potential energy $\left(U\right)$ is given by:

$U = m g h$

where,

$m$ is the mass of the object,

$g$ is the acceleration due to gravity, $= 9.81 \frac{m}{s}$

and $h$ is the object's height above the ground.

Substituting the given values in the above equation,

$U = 29 \cdot 9.81 \cdot \frac{5}{6}$

$U = 237.075 J$
