When Danny Diver who weighs 500 N steps off a diving board 10 m above the water, he hits the water with kinetic energy of

5000 J

Explanation:

Given that,

Weight of Danny Diver, F = 500 N

He steps off a diving board 10 m above the water

We need to find the kinetic energy of the water with which it hits. Let its is K. It is given by :

E = mgh

Where g is acceleration due to gravity

So, he hits the water with kinetic energy of 5000 J.
