3. (15 pts) Consider the arrangement of pulleys and blocks shown in the figure below. The pulleys are assumed massless and frictionless and the connecting strings are massless and unstretchable. Denote the respective masses as ma and mß. The uppermost pulley in the figure is free to rotate but its center of mass does not move. All pulleys have the same radius R.

A window washer of mass M is sitting on a platform suspended by system of cables and pulleys as shown
A window washer of mass M is sitting on a platform suspended by system of cables and pulleys as shown(Intro1 figure). 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 AFind 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.

speed? (b) To lift the canister by 4.0 cm, how far must you pull
the free end of the cord? During that lift, what is the...
