Problem: A 67.6 kg person jumps from rest off a 2.91 m-high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 1.07 m under the surface of the water. This force is non conservative.
Part A: Determine the magnitude of the average force that the water exerts on the diver.
I need help to find the magnitude of the average force that the water exerts on the diver.
