Chapter 4, Problem 87P
Two blocks of mass m1 = 2.5 kg and m2 = 3.5 kg rest on a double inclined plane with equal angles (Fig. P4.87). The blocks are connected by a string that passes over a pulley, and the blocks are in motion. Consider two different scenarios: (1) there is a coefficient of friction μK between m1 and the plane, and there is no friction between m2 and the plane; and (2) there is a coefficient of friction μK between m2 and the plane, and there is no friction between m1 and the plane. In which scenario is the acceleration of the blocks larger?
