Calculate the change in velocity required in changing the position of a satellite in an orbit by 90 degrees. The initial and final orbit is circular around the Earth with a 15000 km radius. Calculate the delta velocity, semi-major axis and period for a transfer orbit that will change the location by + 90 degrees and the same data to move the location by -90 degrees. The action shall use a Hohmann maneuver orbit. Calculate the total delta V required to make each change.
