Question

Assume that b=0.22m and that the coefficient of kinetic friction between the rope and the inclined surface is μk=0.47. Let y (in metres) be the distance travelled by the rope after it has been released from rest.

A rope of length L = 1.5 m and mass m = 2.3 kg is initially at rest and can slide on an inclined
surface with incline 0 = 25° 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 = 0.61.
0.
