Question

A 66.0 kg diver is on a diving board, which is 1.10 m above the water. He falls at a speed of 9.10 m/s. Calculate his kinetic energy as he hits the water.

I know KE is 1/2mv^2, but how can I find KE when height is involved?

Answer 1

You have the potential energy: mgh.

Set that potential energy equal to 1/2 m v^2

Answer 2

Thanks. :)
