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.

the independent variable, or the one that is intentionally manipulated is the speed.
