A thin spherical shell lying on a rough horizontal surface is hit by a cue in such a way that the line of action passes through the centre of the shell. As a result the shell starts moving with a linear speed V with out any initial angular velocity. Find the speed of the shell after it starts pure rolling on the surface .
