Page < 10. Three children are trying to balance on a seesaw, which includes a fulcrum rock acting as a pivot at the center, and a very light board 3.2 m long . Two playmates are already on either end. Boy A has a mass of 45 kg, and boy Ba mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw? Draw a diagram m = 45 kg m = 35 kg m= 25 kg Find the axis of rotation; calculate the torques around it.
