Two boxes are attached by a taut line that is threaded over a pulley of radius 13 cm and mass 100 g. The larger box has a mass of 849 g and lays on a level surface with friction coefficient 0.24. The smaller box has a mass of 341 g and sits on a frictionless incline of grade 0.82.
(a) What is the acceleration of the boxes?
(b) What is the maximum mass for the larger block so that it slides?
(c) If the pulley were massless, what would the acceleration of the boxes be?
(d) What is the maximum mass for the larger block so that it slides with the massless pulley?
