Homework Statement
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).
Homework Equations
KE=(1/2)mass x speed squared
The Attempt at a Solution
I don't know how to find the Kinetic energy using the equation without knowing the speed.
