As shown in figure-5.72 the solid disc and pulley have the same radii and same mass distribution. The solid disc, pulley and the block have equal masses. The plane has a slope of `30^(@)`.The disc rolls on the incline without slipping or loss of energy. Find the acceleration of the hanging block. Consider there is no shipping of string over pulley surface. Take g= 10 m/`s^(2)`.
