Two students sit on a see-saw. Archie is a hulking football player with a mass of 120 kg. Clementine is a dainty cheerleader with a mass of 40 kg. The see-saw is 3.5 m in total length with the fulcrum at the center. If Clementine sits at the end on one side, where must Archie sit relative to the center to keep the see-saw balanced? Why?
