Two manned satellites approaching one another, at a relative speed of 0.500 m/s, intending to dock. The first has a mass of 4.50 10³ kg, and the second a mass of 7.50 10³ kg.

(a) Calculate the final velocity (after docking) in m/s by using the frame of reference in which the first satellite was originally at rest. (Assume the second satellite moves in the positive direction. Include the sign of the value in your answer.)

Answer _____m/s

(b) What is the loss of kinetic energy (in J) in this inelastic collision?

Answer ______J

(c) Repeat both parts by using the frame of reference in which the second satellite was originally at rest.

Final velocity (m/s) ________

Loss of kinetic energy (J) ________ J

Please Explain why the change in velocity is different in the two frames, whereas the change in kinetic energy is the same in both.
