The maximum acceleration a human body can withstand is 10 g, where g = 9.8 m/s^2. Therefore, the maximum acceleration a human body can withstand is (10)(9.8 m/s^2) = 98 m/s^2.

Using Newton's second law, F = ma, we can calculate the net force required to produce this acceleration for a 50-kg person:

F = ma = (50 kg)(98 m/s^2) = 4900 N

Therefore, we need a net force of 4900 N to produce an acceleration of 10 g for a 50-kg person. This is closest to option C) 5000 N.
