A rocket is at rest in space relative to the Earth and has a total mass (including propellant) of M = 2.55 x 105 kg. The engines consume fuel at a constant rate of 480 kg/s, and it leaves the rocket %3D nozzle with an exhaust velocity of 5.35 km/s. If the rocket has a "main burn" for 250 s, what is the change in the rocket's velocity in km/s?
