- Two children with masses of 24 kg and 34 kg are sitting on a balanced seesaw. If the heavier child is sitting O.8 m from the center, at what distance from the center is the lighter child sitting? Your answerarrow_forwardTwo kids are playing on a seesaw on the school playground. The first kid (of mass 50 kg) sits 2 meters from the fulcrum. The other child (who has a mass of 70 kg) sits on the other side of the seesaw. How far away from the fulcrum does the second child need to sit in order to balance the seesaw?
