A rocket is traveling horizontally over the surface of Mars as indicated in the figure to the right, moving at a speed VR = 100 m/s relative to the surface. The exhaust gas being expelled from the rocket is traveling at a speed of VG/R = 30 m/s, relative to the rocket. VR VG/R (a) Determine the velocity (speed and direction) of the exhaust gas relative to the ground (i.e., the absolute velocity of the exhaust) at this instant. (b) If the exhaust gas temperature is TG = 3500 K, and the exhaust nozzle area is A = 2 m², determine the mass flow rate of gas exiting the rocket. Assume a Mars atmospheric pressure Patm,Mars = 600 Pa, and a gas constant RMars = 188 J/(kg k).
