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 3.2 m long. Two playmates are A m = 45 kg │x➡ Part A B m = 35 kg m = 25 kg already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw? Express your answer to two significant figures and include the appropriate units.
