(i) A particle P, of mass 2m, lies on a rough horizontal table. P is connected by a light inextensible string passing over a smooth pulley fixed at the edge of the table to another particle Q, of mass 5m, hanging freely. The system is released from rest with the string taut and the hanging part vertical. If the acceleration of the system is of magnitude , find
