A rocket is moving away from the solar system at a speed of6.0 * 103 m/s. It fires its engine, which ejects exhaust with a speedof 3.0 * 103 m/s relative to the rocket. The mass of the rocket atthis time is 4.0 * 104 kg, and its acceleration is 2.0 m/s2. (a) What isthe thrust of the engine? (b) At what rate, in kilograms per second,is exhaust ejected during the firing?
