To find the net force, we can use Newton's second law of motion, which states that force (F) equals mass (m) times acceleration (a):

F = ma

We are given the acceleration (a) of 10 g, which we need to convert to meters per second squared (m/s^2) since the units of force are in newtons (N) and meters per second squared (m/s^2).

10 g = 10 x 9.8 m/s^2 (where 9.8 m/s^2 is the acceleration due to gravity)

F = 50 kg x 10 x 9.8 m/s^2

F = 4900 N

Therefore, the net force required to produce an acceleration of 10 g on a 50-kg person is about 5000 N.

The answer is C.
