Question

A block of mass 30 m can’t move without friction on a horizontal table. Block is attached to another block of mass by 8 m by a cord that passes over a frictionless pulley as shown. If the masses of the cord and the pulley our neglect a bowl what is the magnitude of the acceleration of the descending block hole?If the masses of the cord in the pulley are negligible what is the magnitude of the acceleration of the descending block?
