Example 2:<br />

A 55.0kg diver is st<strong>and</strong>ing on a diving platform <strong>and</strong> has a<br />

gravitational potential energy of 5.40 x10 3 J. What is the vertical<br />

height of the platform?<br />

E p = mgh<br />

h = E p / mg<br />

= (5.40 x 10 3 J) / (55.0kg)(9.81m/s 2 )<br />

= 10.0m<br />

The vertical height is 10.0m.
