1. The distance between a carbon atom (m =
12 u) and an oxygen atom (m = 16 u) in the CO molecule is 1.13 X 10-10m.
How far from the carbon atom is the center of mass of the molecule?

2. A square uniform raft, 18 m by 18 m, of
mass 6200 kg, is used as a ferryboat. If three cars, each of mass 1350 kg,
occupy the NE, SE, and SW corners, determine the cm of the loaded ferryboat
relative to the center of the raft.
