A rocket is moving away from the solar system at a speed of 6.0x103 m/s. It fires its rocket

engine, which ejects exhaust with a relative velocity of 3.0x103 m/s. The mass of the rocket at this

time is 4.0x104

kg, and it experiences an acceleration of 2.0 m/s2

. (a) What is the velocity of the

exhaust relative to the solar system? (b) At what rate was exhaust ejected during the firing?
