Assumethe orbital of a lunched satellite around the earthiscircular.
(a)Show that there is only one speed that a satellite canhave if thesatellite is to remain in an orbit with
afixed radius and it does not depend on the mass ofthesatellite.
(b)What is the speed and heightHabove the earthâs surfaceat which all synchronoussatellite
(regardless of mass) must be placed in orbit, assumingtheearth is spherical?
(c) Ifa synchronous satellite has amassm. How muchadditional kineticenergy is needed for it to escape
fromthe earth?
