A uniform solid sphere of radius `r` is rolling on a smooth horizontal surface with velocity `V` and angular velocity `omega=(V=omegar)`. The sphere collides with a sharp edge on the wall as shown in Fig. The coefficient of friction between the sphere and the edge `mu = 1//5`. Just after the collision the angular velocity of the sphere becomes equal to zero. The linear velocity of the sphere just after the collision is equal to
