A new communications satellite is being sent into space. The rocket carrying the satellite has a mass of 2.04 x 106 kg. The engines expel 3.7 x 103 kg of exhaust gas during the first second of liftoff giving the rocket a velocity of 5.7 m/s [up]. At what velocity is the exhaust gas leaving the rocket engines? Ignore the change is mass due to the fuel being consumed. The exhaust gas needed to counteract the force of gravity has already been accounted for and should not be part of this calculation. Show all calculations.
