A Satellite That Weighs 4900 N on the Launchpad Travels

Short Answer

A satellite that weighs 4900 N on the launchpad travels around the earth's equator in a circular orbit with a period of 1.667 h.The earth's mass is 5.97 × 10²⁴ kg,its equatorial radius is 6.3 × 10⁶ m,and G = 6.67 × 10^-11 N • m²/kg².
(a)Calculate the magnitude of the earth's gravitational force on the satellite.
(b)Determine the altitude of the satellite above the Earth's SURFACE.
