A drum is made to revolve about its centre by a falling mass as shown. Calculate the velocity of the falling mass and rotating drum when the mass descends 10 m with no frictional losses. Also calculate the energy gained by the drum. DRUM k = 0.3 m M = 15 kg MASS M= 12 kg Figure Q2a R =,0.4 m r = 0.2 m
