(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A high diver, mass 50kg sits atop the diving platform with 10,000 Joules of stored gravitational potential energy (PE). The platform has a height of 20m. The diver makes his leap. When the diver has dropped 3/4 of the height what is diver total energy (KE + PE).

2. Relevant equations

KE=(1/2)mass x speed squared

3. The attempt at a solution

I don't know how to find the Kinetic energy using the equation with out knowing the speed.
