1. The problem statement, all variables and given/known data A uniform plank of length 6.00m and mass 30.0 kg rests horizontally across two horizontal bars of a scaffold. the bars are 4.50 m apart, and 1.50m of the plank hangs over one side of the scaffold. How far can a painter of mass 70.0kg walk on the overhanging part of the plank before it tips? 2. Relevant equations w1*d-w2*d=0 3. The attempt at a solution 70g*d*Na*0-30g+((6.2)-1.5)+Nb*4.5=0 70g*d-30g+((6/2)-1.5)=0 d=(30g*(6/2)-1.5)=0 d=0.6428m Is my answer correct and is meters the right unit d should be in?
