A) a satellite that weighs 4900N on the launchpad travels around the earths equator in a circular orbit with a period of 1.667h. The earth's mass is 5.97*10^24kg, its equatorial radius is 6.3*10^6m and G=6.67*10^-11N*m^2/kg^2. Calculate the magnitude of the earths gravitational force on the satellite.
B) determine the altitude of the satellite above the earths surface.
