Two manned satellites approaching one another at a relative speed of 0.500 m/s intend to dock. The first has a mass of 3.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. Assume that the positive direction is directed from the second satellite towards the first satellite.(b) What is the loss of kinetic energy in this inelastic collision?
