Two manned satellites approaching one another at a relative speed of 0.500 mfs intend to dock. The rst has a mass of 3.50 x 103 kg, and the second a mass of 150 x 103 kg. If the two satellites collide elastically rather than dock, what is their final relative velocity? Adopt the reference frame in which the second satellite is initially:r at rest and assume that the positive direction is directed from the second satellite towards the first satellite. E m
