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 = 41.0°. The objects are released from rest, and m2 slides 1.80 m down the slope of the incline in 4.70 s.
Determine the coefficient of kinetic friction between m2 and the incline.
