Two blocks of mass 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 and the plane, and there is no friction between and the plane; and (2) there is a coefficient of friction and the plane, and there is no friction between and the plane. In which scenario is the acceleration of the blocks larger?
