Two manned satellites approaching one another at a relative speed of 0.200 m/s intend to dock. The first has a mass of 3.50e3 kg and the second a mass of 7.50e3 kg. Assume that the positive direction is directed from the second satellite towards the first satellite. Calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest. What is the loss of kinetic energy in this Inelastic collision?
