Suppose a ball of mass 0.2kg strikes a free-floating uniform rod (of mass 0.4kg and length 1.2m) a distance of 0.3m from its center of mass at a right angle with initial speed 14 m/s. The ball ricochets off the rod, with final velocity pointing in the opposite direction of its initial velocity, and the rod begins to move and rotate. What is the final speed of the ball, the final speed of the center of mass of the rod, and the final angular velocity of the rod?
