A rope of length L = 1.3 m and mass m = 1.5 kg is initially at rest and can slide on an inclined surface with incline 0 = 30° as shown in the figure. Assume that the part of the rope that is not on the inclined surface hangs down vertically at all times and that the static friction coefficient between the rope and the surface is μ = 0.66.
