A 66 kg diver steps off a 13 m tower and drops, from rest, straight down into the water. If he comes to rest 4.4 m beneath the surface, determine the average resistance force exerted on him by the water.

Answer 1

force*distance=mgh Now there is a trickher, h is not 13m he actually fell 13+4.4m, but I think here I would ignore it, because if you include that, you need to include the force of bouyancy, which you have little info to do.
