Two boxes are on opposite ends of a plank that is 3.0 m long. the plank is supported in the middle by a fulcrum. the box on the left has a mass, m1, of 25 kg. the box on the right has a mass, m2, of 15 kg. use the formulas below to determine how far the fulcrum must be positioned from the right side of the plank in order to balance the masses horizontally. (hint: g=9.8m/s2)
fg of m1=(m1)(g)
fg of m2=(m2)(g)
distance from the right= (fg)m1 ( i ) ÷ (fg)m1+(fg)m2
