A window washer of mass M is sitting on a platform suspended by a
system of cables and pulleys as shown (Figure 1). He is pulling on the
cable with a force of magnitude F. The cables and pulleys are ideal
(massless and frictionless), and the platform has negligible mass.
Part A
Find the magnitude of the minimum force F that allows the window washer to move upward.
Express your answer in terms of the mass M and the magnitude of the acceleration due to gravity g.
