Three children 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 3.6m long (Fig. 9-50). Two playmates are already on either end. Boy A has a mass of 50-kg, and girl B a mass of 35-kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw?
