10. A painter of mass M stands on a platform of mass

10. A painter of mass M stands on a platform of mass m and pulls himself up by two ropes which hang over smooth and light pulleys, as shown. He pulls each rope with constant force F downwards and accelerates upward with a uniform acceleration a. Find a, neglecting the fact that nobody could do this for long. Figure 8: Diagram Q11.
