# A ball of mass M collides head-on and inelastically with a ball of mass 4M . Before the collision, the ball of mass M is moving to the right at speed v0 and the ball of mass 4M is moving to the left at the same speed v0. After the collision, the ball of mass 4M is moving to the left at speed v0/2. What is the ratio of the final kinetic energy to the initial kinetic energy?
