A ball is given a velocity v and angular velocity such that the ball rolls purely on a plank whose upper surface is rough enough to prevent slipping but lower surface contact with the ground is smooth. No other force is acting on system.

A uniform circular disc of mass M and radius R rolls without slipping on a horizontal surface. If the velocity of its centre is v0 then the total angular momentum of the disc about a fixed point P at a height 3/2 R above the centre C.
