Is the center of mass system an inertial frame?

Can you please answer this question ASAP A and B have same mass. Initially, B is at rest and A is moving at 5 m/s. If restitution coefficient is 1 , what is the velocity (m/s) for B after impact._____

Kindly provide a CLEAR and COMPLETE solution. Please answer ASAP if possible, thanks.

Two manned  satellites approaching one another at a relative speed of 0.150M/S intend to dock. The first has a mass of 3.00×10^3 kg, the second a mass of 7.50 x 10^3 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 set a lot was originally at rest. m/s ? (b) what is the loss of kinetic energy in this inelastic collision? j ? (c) repeat both parts in the frame of reference in which the second satellite was originally at rest. Final velocity m/s ? loss of kinetic energy j ? explain why the change in velocity is different in the two frames, where areas the change in kinetic energy is the same in both. I used ^ to show exponents

7) Two manned satellites approaching one another, at a relative speed of 0.550 m/s, intending to dock. The first has a mass of 5.00 ✕ 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.)  _____m/s   (b) What is the loss of kinetic energy (in J) in this inelastic collision? _____ J   (c) Repeat both parts by using the frame of reference in which the second satellite was originally at rest. final velocity (m/s)  _____ m/s loss of kinetic energy (J) _____ J Explain in detail why the change in velocity is different in the two frames, whereas the change in kinetic energy is the same in both.

A spaceship with fuel is initially at rest at point CG.  Fuel is ejected at the back to propel the payload to the forward direction.  After a long time, the total fuel ejected out has a mass of 1e6 pounds, and center of gravity moving backward at 20 m/s.  The forward speed of the payload relative to CG is 150 m/s.  The payload mass is _____ pounds.

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.

Consider as a system the Sun with Mars in a circular orbit around it. Find the magnitude of the change in the velocity of the Sun relative to the center of mass of the system during the time Mars completes half an orbit. Assume the mass of the Sun is 5.68 x 1029 kg, the mass of Mars is 6.42 x 1023 kg, its period is 5.94 x 107 s, and the radius of its orbit is 2.28 x 10¹¹ m. Ignore the influence of other celestial objects. 19.4 x m/s
