Calculate the distance from the Earth for a geosynchronous satellite orbit. Express the result in units of the radius of the Earth.
T^2 = 4pi^2*R^3/(GM)
T = 24*60*60 = 86400 seconds
R = ?
G = 6.67*10^-11
M = 5.98*10^24
solve for R which is about 42250 km
subtract the radius of earth to find the distance from earth (6378 km)
