A new communications satellite is being sent into space. The rocket carrying the satellite has a mass of 2.04x10^6 kg. The engines expel 3.7x10^3 kg of exhaust gas during the first second of liftoff giving the rocket a velocity of 5.7m/s [up]. At what velocity is the exhaust gas leaving the rocket engines? Ignore the change in 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.



I have been stuck on this question for this whole week. Please help!
