A satellite of mass 200 kg is launched from the site on Earth's equator to an orbit at 185 km above the surface of Earth. (The mass of Earth is 5.98 x 1024 kg, and the radius of Earth is 6.38 x 103 km.)
(i) Supposing a circular orbit, determine the orbital period of the satellite?
(ii) Determine the speed of satellite in the orbit?
(iii) Determine the minimum energy essential to place the satellite in orbit, supposing no air friction?
