A81.0 kg diver falls from rest into a swimming pool from a height of 4.70 m. it takes 1.84 s for the diver to stop after entering the water. find the magnitude of the average force exerted on the diver during that time.

Explanation:

The given data is as follows.

             height (h) = 4.70 m,    mass = 81.0 kg

              t = 1.84 s

As formula to calculate the velocity is as follows.

            = 2gh

                       =

                       = 92.12

As relation between force, time and velocity is as follows.

                     F =

Hence, putting the given values into the above formula as follows.

                  F =

                     =

                     = 4055.28 N

Thus, we can conclude that the magnitude of the average force exerted on the diver during that time is 4055.28 N.
