Three children are playing on a see saw. The child on the left has a mass of 45.0 kg and the middle child has a mass of 20.0 kg and the child on the right has a mass of 25.0 kg. THe center of mass of the child on the left is at a distance of 1.50 meters from the fulcrum. The center of mass of the child in the middle is a distance of 1.20 meters from the fulcrum. Where is the center of mass of the child on the right when the see saw is balanced?
