A rocket is moving away from the solar system at a speed of 6.0 x 103 m/s. It fires its engine, which ejects exhaust with a speed of 3.0 x 103 m/s relative to the rocket. The mass of the rocket at this time is 4.0 x 104 kg, and its acceleration is 2.0 m/s2.

(a) What is the thrust of the engine?

(b) At what rate, in kilograms per second, is exhaust ejected during the firing?
