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