A hollow smooth U tube of mass 2m is lying at rest on a smooth horizontal surface Two small smooth balls of mass m moving with velocity u enter into the tube simultaneously Assuming all collisions to be elastic find out a final velocity of balls after long time b final velocity of tube after long time c minimum kinetic energy of the system during the process of collisions 2m
