Homework Help: Resistance force and work

  1. Nov 2, 2005 #1
    A 70 kg diver steps off a 10m tower and drops straight down into the water. If he comes to rest 5m below the surface determine the average resistance force exerted on him by the water.


    I can determine that the PE should be 10290 J. But I'm stuck for what exactly to do next... Since there's no velocity given I am lost.

    F = ma, find his deceleration.
