The spheres are all 6.5 grams, such that the system of the 4 spheres is 26 grams. The spheres are moving together along a track, before hitting a junction (which you can treat as theorigin). When the system of spheres gets to the junction, one sphere breaks free, moving 6 meters north. Another sphere moves west 8 meters and north 2 meters. The last two spheres both move east 5 meters and south 4 meters. What are the x and y coordinates of the center of mass of the system?
