A Mars rover has collected and analyzed several samples from the surface and atmosphere of Mars. NASA has processed most of the data but is looking for help in identifying two of the remaining elements from the samples. They know that both elements are main group elements belonging in either Group 2 or Group 18. Group 2 elements are highly reactive, while Group 18 elements are unreactive. Group 2 elements are also solid at room temperature, while Group 18 elements are gases at room temperature. The following information about unknown Element J and unknown Element Q has just arrived for you to examine Claim, evidence, reasoning

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 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. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
