Question

Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The object m1 is held at rest on the floor, and m2 rests on a fixed incline of θ = 39.0°. The objects are released from rest, and m2 slides 1.80 m down the slope of the incline in 4.50 s.

(a) Determine the acceleration of each object. (Enter the magnitude only.)

(b) Determine the tension in the string. (Enter the magnitude only.)

(c) Determine the coefficient of kinetic friction between m2 and the incline
