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
