2. Material has been observed in a circular orbit around a black hole some five thousand light-years away from Earth. Spectroscopic analysis of the material indicates that it is orbiting with a speed of 3.1 x 107 m/s. If the radius of the orbit is 9.8 x 105 m, determine the mass of the black hole, assuming the matter being observed moves in a circular orbit around it. 3. What is the difference between a geosynchronous orbit and a geostationary orbit? 4. The International Space Station orbits Earth at an altitude of ~ 350 km above Earth's surface. If the mass of the Earth is ~ 5.98 x 1024 kg and the radius of Earth is ~ 6.38 x 106 m, determine the speed needed by the ISS to maintain its orbit. (Hint: riss = Earth + altitude) 2.
