Example 2.9.4



 A satellite is traveling at a constant speed in a circular orbit 400 miles above the surface of the earth where the acceleration of gravity is 30 ft per ${\mathrm{sec}}^{2}$.  If the radius of the earth is taken as 4000 miles, what is the speed (in miles per hour) of the satellite?
