344 Angular Momentum P11.48 (a) τ =−= MgR MgR 0 (b) = dL dt , and since = 0 , L = constant. Since the total angular momentum of the system is zero, the monkey and bananas move upward with the same speed at any instant, and he will not reach the bananas (until they get tangled in the pulley). Also, since the tension in the rope is the same on both sides, Newton’s second law applied to the monkey and bananas give the same acceleration upwards. FIG.
