Superman HW Problem
It is well known that bullets and other missiles fired at
Superman simply bounce off his chest
Suppose that a gangster sprays Superman's chest with 6 g bullets at the rate of 120 bullets/min, the speed of each bullet being 600 m/s. Suppose too that the bullets rebound straight back with no change in speed. What is the magnitude of the average force on Superman's chest from the stream of bullets?
