What is the orbital speed of a satellite of mass 490 kg in geostationary orbit?

• Physics -

the distance in one orbit: 2PI(re+h)
period=24 hrs (convert to seconds).

v=2PI(re+h)/period

gravity acceleration= centripetalacc
9.8 re^2/(re+h)^2 = v^2 (above)/(re+h)

solve for h re is radius earth.
then solve for V
