A 62.0 kg diver falls from rest into a swimming pool from a height of 3.50 m. It takes 1.92 s for the diver to stop after entering the water. Find the magnitude of the average force exerted on the diver during that time.

The impluse given to the diver is equal to the momentum change.

First, find the velocity at impact.

vf=sqrt(2*g*h)

Then, in the water,

Forceaverage*time=mass*changeinvelocity.
