John’s mass is 81.0 kg, and Barbara’s is 62.4 kg. He is standing on the x axis at xJ = +9.41 m, while she is standing on the x axis at xB = +4.34 m. They switch positions. How far and in which direction does their center of mass move as a result of the switch?
Distance moved by center of mass =? m toward the origin
