the distance between them is constant, but the cm will be closer to the larger mass
separation ... 9.01 - 4.65 = 4.36 m
cm ... 85.4 d = 55.2 (4.36 - d)
... d is the distance from John
when they switch, the cm will be closer to the origin
... because John will be closer to the origin
Johns mass is 85.4 kg, and Barbars is 55.2 kg. He is standing on the x axis at xJ = +9.01 m, while she is standing on the x axis at xB = +4.65 m. They switch positions. How far and in which direction does their center of mass move as a result of the switch?
