A 61.7 kg person jumps from rest off a 2.98 m-high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 1.19 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver. This force is nonconservative.
I have gone through multiple times different ways. Finding force when she hits the water, the time it takes and then ended up believing I have to divide her force by time.??
