A painter (mass 72 kg) is walking along a trestle, consisting of a uniform plank (mass 28.5 kg, length 6.000 m) balanced on two sawhorses. Each sawhorse is placed 1.13 m from an end of the plank. A paint bucket (mass 4.02 kg, diameter 24 cm) is placed as close as possible to the right-hand edge of the plank while still having the whole bucket in contact with the plank. (a) How close to the right-hand edge of the plank can the painter walk before tipping the plank and spilling the paint? (b) How close to the left- hand edge can the same painter walk before causing the plank to tip?
