A 60 kg painter is on a scaffold supported from above by ropes. The scaffold has a mass of 25 kg and is uniformly constructed. There is a 4.0 kg pail of paint off to one side, as shown in the figure. Can the painter walk safely to both ends of the scaffold? If not, which end(s) is dangerous and how close to the end can he approach safely?
