A winch is lowering a mass M = 82.3 kg
down a = 17.8° incline at 3.67 m/s as indicated in the drawing.
The force F
provided by the cable from the winch
is acting parallel to the surface of the
incline. There is a coefficient of kinetic
friction of : = 0.209 between M and the surface.
(A) Draw the free-body diagram for M, being careful to show all forces in terms of their components.
(B) Calculate the force F from the winch if M has a constant velocity.
