Homework Help: Physics

Posted by Evan on Wednesday, December 5, 2012 at 2:12pm.

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 8 g bullets at the rate of 110 bullets/min, the speed of each bullet being 550 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?
