A window washer on a scaffold hoists the scaffold up the side of a building by pulling down on a rope that runs over a pulley and connects back to the top of the scaffold. The combined mass of the worker and the scaffold is 95kg, and the washer pulls on the rope with a force of 800N.
What is the acceleration of the scaffold?

A window washer pulls a rubber squeegee down a very tall vertical window. The squeegee has mass 150 g and is mounted on the end of a light rod. The coefficient of kinetic friction between the squeegee and the dry glass is 0.790. The window washer presses it against the window with a force having a horizontal component of 3.00 N. If she pulls the squeegee down the window at constant velocity, what vertical force component must she exert? The...

A painter supported on a scaffold supported by two pulleys on the top. The rope goes from one end of the scaffold, wraps over the top pulley, then wraps under a pulley on the scaffold, and around a cranking wrench. The painter cranks the wrench which creates a force of tension of 350 N going out towards the pulley. If this force is sufficient enough to cause the scaffold and painter to rise with a constant velocity, what is the...

The fiqure shows a man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 78.4 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of 1.42 m/s2? (Hint: A free-body diagram can really help.) Problem continues below...

A bosun’s chair is a device used by a boatswain to lift himself to the top of the mainsail of a ship. A simplified device consists of a chair, a rope of negligible mass, and a frictionless pulley attached to the top of the mainsail. The rope goes over the pulley, with one end attached to the chair, and the boatswain pulls on the other end, lifting himself upward. The chair and boatswain have a total mass M = 95.7...
