A one-stage rocket takes off from Space and is tasked withentering into a geosynchronous (the
period of orbit is one day) low earth orbit at an altitude of2,000km above the surface of the Earth. The mass of the
rocket is 550,000kg,
a) At what final speed does the rocket need to be moving toachieve the specified orbit?
b) If the exhaust velocity of the fuel is 2.20x103m/s whatpercentage of the rocket’s mass must be fuel?
c) Given that the rocket expends fuel at a rate of 1.4x104kg/swould this rocket be appropriate for manned flights?
