A satellite is in a circular parking orbit with an altitude of 210 km and an inclination of 28 degrees. Calculate the total velocity change required to transfer the satellite to a zero-inclination circular geosynchronous (geostationary) orbit using a Hohmann transfer followed by a plane change at apogee. [Note: radius of geostationary orbit is 42,164 km.]
