Three boys are trying to balance on a seesaw, which consists of a fulcrum rock, acting as a pivot at the center, and a very light board L = 3.52 m long, see figure below.
Two boys are already on either end. One has a mass of m1 = 53.0 kg, and the other a mass of m2 = 32.8 kg. How far from the center should the third boy, whose mass is m3 = 23.0 kg, place himself so as to balance the seesaw?
i know how to do it but with just to boys, but with three boys idont have the minimum idea... can anyone helps me?...
