Problem

At an altitude where the acceleration due to gravity is

3.0\,\text{m\,s}^{-2}

, a satellite moves in a circular orbit around Earth. Using

g = 9.8\,\text{m\,s}^{-2}

and Earth’s radius

R = 6400\,\text{km}

, determine the orbital speed of the satellite. a)

7.9\,\text{km\,s}^{-1}

5.9\,\text{km\,s}^{-1}

11.2\,\text{km\,s}^{-1}

4.4\,\text{km\,s}^{-1}
