A uniform sphere with mass 2m and radius 2r is at rest in a place where no external forces are applied . A second sphere of mass m and radius r moves towards it with a velocity v(without rotating).The two spheres stick together and then continue their motion as one body. What is the distance of the cm of system from the centre of bigger sphere at the time of collision?
