A spring gun shoots out a plastic ball at speed v. The spring is then compressed twice the distance it was on the first shot. a) By what factor is the spring's potential energy increased? Explain. b) By what factor is the ball's speed increased? Explain.

Ball and Spring Gun a ball of mass $m$ is shot with speed $v_{1}$ into the barrel of a spring gun of mass $M$ initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. Assume that the increase in ther- mal 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?
