A high diver of mass 60.0 kg steps off a board 10.0 m above the water and falls vertical to the water, starting from rest. If her downward motion is stopped 1.80 s after her feet first touch the water, what average upward force did the water exert on her?
Fav*(1.80 s) = Momentum when entering water
