1. The problem statement, all variables and given/known data A 59-kg window-washer stands on a 17-kg platform. The platform is fixed to a rope that passes over a pulley attached to the ceiling, which allows the window-washer to raise himself and the platform. (a) To accelerate himself and the platform at a rate of 0.84 m/s2, with what force must he pull on the rope? (b) When his velocity reaches 2.3 m/s, he pulls so he and the platform go up at a constant speed. What force is he exerting on the rope? 2. Relevant equations 3. The attempt at a solution I thought since there was only one pulley the ratio of the force of the window washer pulling on the rope to the net force due to tension on him and the platform would be 1:1. Evidently this is not the case. Is the force applied by the washer on the rope halfed by the pulley. If so why is this the case?
