A rocket is moving away from the solar system at a speed of 6.0x10^3 m/x. It fires its rocket engine, which ejects exhaust with relative velocity of 3.0x10^3 m/s. The mass of the rocket at this time is 4.0x10^4 kg, and it experiences an acceleration of 2.0 m/s^2. What is the velocity of the exhaust relative to the solar system? and At what rate was the exhaust ejected during the firing? I have no idea how to even start this problem. Any help would be great.
