2. A painter uses a platform/rope/pulley system to raise/lower himself along the side of a house. The painter has a mass 9M and the platform has a mass of 3M. The painter pulls downward on the rope with a force of 5Mg. (Newton's 3rd law should tell you what the tension is.) The mass and friction of the pulley is negligible. a. Draw free body diagrams (FBD) showing the forces on the system of the painter and platform, the painter, and the platform. Make sure all action reaction pairs are given the same label and masses are labeled correctly. b. What is the magnitude and direction of the acceleration of the painter in terms of M and/or g? magnitude =, direction (up/down) = c. What is the magnitude and direction of the force that the painter exerts on the platform? magnitude =, direction (up/down) =. d. Assume the painter starts at rest and pulls with this tension for 3 seconds. How far has the painter traveled during this time?
