a1 S m T mg R M Mg a2 A cord is wrapped around a homogeneous disk of radius R and mass M. It passes over a smooth pin. A block of mass m is attached to its second end. A disk goes down unwrapping from the cord and pulls a block along the horizontal rough surface of friction coefficient u. Find the linear acceleration a1 of the block (in this case it is not the same as the acceleration az of the center O of a disk). Given: m, M, R, u, g ai =?
