Bullets can’t penetrate Superman’s chest. Assume that Superman, with mass 104 kg, while not moving, is struck by a 4.20-g bullet moving with a speed of 835 m/s. The bullet drops straight down with no horizontal velocity. How fast was Superman moving after the collision if his super feet are frictionless?
