Objects of masses m = 4.00 kg and m, = 9.00 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.70. The object m, is held at rest on the floor, and m, rests mi on a fixed incline of 0 = 40.0°. The objects are released from rest, and m, slides 1.00 m down the incline in 4.00 s. Determine (a) the acceleration of each object, (b) the tension in the string, and (c) the coefficient of kinetic friction between m, and the incline. m2 Figure P4.70
