Answer

39318 Joules/second

Work Step by Step

Since gravitational potential energy is U = mgd, then as the diver falls, the difference in his potential energy would be $\Delta U = mg\Delta d$. The change in his position over time is his velocity, which we are told is 59 m/s. Therefore the potential energy is decreased by 39318 Joules/second
