A rocket traveling 1800 m/s away from the Earth at an altitude of 6300 km fires its rockets, which eject gas at a speed of 1450 m/s (relative to the rocket). Part A If the mass of the rocket at this moment is 2.55×104 kg and an acceleration of 1.9 m/s² is desired, at what rate must the gases be ejected? Express your answer using two significant figures.
