4. A painter of mass 70.0 kg stands on a platform of mass 75.0 kg and pulls on two ropes which hang over pulleys. He pulls each rope with a force of 750.0 N. Assuming a coordinate system where +y is up, calculate the y-component of the acceleration ay. ay can either be positive or negative depending on the direction of the acceleration
