A "double satellite" is launched into space. It consists of a satellite of mass m and another satellite of mass 5m. The connecting mechanism of these satellites is an explosive bolt and a compressed spring, both of negligible mass. The bolt is exploded and the satellites drift apart having been pushed by the spring. When the less massive satellite has moved a distance of 2.5 m from the center of
mass of the double satellite, how far away from it is the satellite of greater mass? a. 3.0 m c. 0.10 m b. 12 m d. 0.50 m
