5. Assume the pulley in the picture below is an ideal, massless pulley.
(a) Draw a free body diagram on the 5 kg mass. Assume that it is freely hanging by the string.
(b) Draw a free body diagram on the 2 kg mass (include friction).
(c) If friction is preventing the blocks from moving, what is the force of tension in the string?
(d) How large is the force of friction to stop the heavy block from falling?
2 kg
5 kg
