A block A of mass m is lying on a rough horizontal surface. Another block B of mass 2m having velocity 10m/s just before collision, makes head on collision with stationary block A. The coefficient of restitution between blocks is 0.5, and the coefficient of friction between blocks and ground is 0.3. Find the distance between the blocks when they stop. A. 12.5m B. 13.5m C. 14.5m D. 15.5m
