Take the y=√(1-x^2) and the density of the disk to be δ = 1.Bullets and other missiles fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman’s chest with bullets of mass m at the rate of n. The speed of each bullet is v and the angle of each bullet with respect to the plane of superman’s chest is θ. Suppose too that the bullets bounce off his chest specularly with no change in speed. Find the average force exerted by the stream of bullets on Superman’s chest. The answer is F=mn2vsin(theta). Can someone explain with steps, how did we get this?
