A painter on a platform raises herself by pulling on a rope connected to a system of pulleys asshown above. The painter and the platform combined weight is 100 kg. The painter applies atension force of magnitude T=200N to one end of the rope. We want to find the combinedacceleration of the unit.1) Draw a free body diagram of forces acting on the combined system of the painter andplatform. Look closely at the rope-pulley system and count the number of ropes. (1point)2) Using the Newton's second law find the acceleration a of the whole unit. (2 points)3) The painter has reached the desired height and attached her end of the rope to theplatform. Compute the tension in the rope. (2 point)If the rope on that the painter was pulling on now extends to the ground and is pulledby a co-worker with the same amplitude T=200N, what is now the acceleration of thewhole unit?
