SUMMARY
The average resistance force exerted on a 70 kg diver entering water from a height of 10 meters can be calculated using principles of physics. The potential energy (PE) of the diver at the top is 10,290 J. To find the average resistance force, one must first determine the deceleration of the diver as he comes to rest 5 meters below the surface. Using the formula F = ma, where 'm' is the mass and 'a' is the calculated deceleration, will yield the average resistance force.
