Two bears sit on a see-saw. The see-saw is 3.5 m in total

length with the fulcrum at the center. A 40 kg baby bear sits at the very end of one side. Where should the 120 kg father bear sit relative to the center to keep the see-saw balanced?

Answer:

Step-by-step explanation:

For the see-saw to be balanced, take moment at the fulcrum:

40g * 3.5/2 = 120g * distance

distance = 1.167m from the center
