Two manned satellites approach one another at a relative velocity of v = 0.250 m/s
Two manned satellites approach one another at a relative velocity of v = 0.250 m/s, intending to dock. The first has a mass of mı = 4.00 x 10² kg and the second a mass of m2 = 7.50 x 10 kg. If the two satellites collide elastically rather than dock, what is their final relative velocity? final relative velocity: _______ m/s
