A painter (of mass 75 kg) needs to reach out from a scaffolding to paint the side of a building, so he lays a plank across two bars of the scaffolding, and puts a heavy bucket of mass 72 kg directly over one of the bars (see figure). You can assume the plank is massless, and is long enough to reach to the other building. If the bars are separated by a distance 2.6 m, how far, d, from the bar on the the right can the painter walk before the plank starts to fall? d =
