Objects of masses m = 4.0kg and m 9.0 kg are 1 2 connected by a light string that passes over a frictionless pulley in the figure. The object m, is held at rest on the floor, and m, rests on a fixed incline of 2 0 = 40.5°. The objects are released from rest, and m 2 slides 1.3m down the slope of the incline in 3.95s. (a) m Find the magnitude of the acceleration (in ) of either S 2 mass. (b) Find the coefficient of kinetic friction between m and the incline. 2
