A block of mass m is attached to one end of a light string which is wrapped on a disc of mass 2m and radius R. The total length of the slack portion of the string is 1. The block is released from rest. The angular velocity of the disc just after the string becomes taut is

The block of mass m is at rest. Find the tension in the string A .

The block of mass m is at rest. Find the tension in the string A .

A block of mass m is attached at the end of an inextensible string which is wound over a rough pulley of mass M and radius R figure a. Assume the string does not slide over the pulley. Find the acceleration of the block when released.
