Question

A new design of Saturn 18 rocket with mass 1.26 x106 kg has a propulsion engine that can eject gases at a constant speed of 397.5 m/s (vGas) by burning fuel at a rate of 2.15  x10 5  kg/s (dmdT). In full tank, the rocket can carry a fuel of mass 40.5  x10 6  kg.

If this design exceeds the velocity of 11,200 m/s it can can successfully escape Earth's gravity. Determine if this is so. Find its maximum velocity (velyZ). (Pitch Angle = 0)
