Solution
... If we consider just the pulley above the painter’s head, there is a nonzero horizontal force to the left due to the tension in the rope. So the painter must actually pull the rope slightly to the left to balance this force. b) Find the acceleration of the platform. Solution: Let a1 denote the magnit ...
