Suppose an Olympic diver who weighs 54.0 kg executes a straight dive from a 10-m platform. At the apex of the dive, the diver is 10.8 m above the surface of the water.

You may want to reference (Pages 165 - 166)Section 5.1 while completing this problem.

What is the potential energy of the diver at the apex of the dive, relative to the surface of the water?

**Assuming that all the potential energy of the diver is converted into kinetic energy at the surface of the water, at what speed in m/s will the diver enter the water?**
