A disc of mass M and radius R is rolling with angular speed w on horizontal plane as shown. The magnitude of angular momentum of the disc about the origin O is :

A semicircle disc of mass M and radius R is held on a rough horizontal surface as shown in figure. The centre of mass C of the disc is at a distance of (4R)/(3pi) from the point O . Now the disc is released from this position so that it starts rolling without slipping. Find (a) The angular acceleration of the disc at the moment it is relased from the given position. (b) The minimum co-efficient of fricition between the disc and ground so that it can roll without slipping.
