A satellite orbits the Earth in an elliptical orbit. At perigee its distance from the center of the Earth is 22500 km and its speed is 4280 m/s. At apogee its distance from the center of the Earth is 24100 km and its speed is 3990 m/s. Part A Using this information, calculate the mass (in kg) of the Earth.
