a ball of mass m = 60 g is shot with speed vi 22 m/s into the barrel of a spring gun of mass M 240 g initially at rest on a frictionless surface.The ball sticks inthe barrel at the point of maximum compression of the spring. Assume that the increase in thermal energy due to friction between the ball and the barrel is negligible. (a) What is the speed of the spring gun after the ball stops in the barrel? (b)What fraction of the initial kinetic energy of the ball is stored in the spring?
