1. The problem statement, all variables and given/known data While standing on a long board resting on a scaffold, a 70 kg painter paints the side of a house. If the mass of the board is 15 kg, how close to end can the painter stand without tipping the board over? 2. Relevant equations [tex]\tau[/tex]painter = [tex]\tau[/tex]board 3. The attempt at a solution [tex]\tau[/tex]painter = [tex]\tau[/tex]board (rpainter) (70kg) = (1.5 m) (15kg) 70r = 22.5 r=.32 ft. the answer was 1.2 m from left end of board.
