A satellite of mass 205 kg is launched from a site on Earth's equator into an orbit at 185 km above the surface of Earth. (The mass of the Earth is 5.98 1024 kg, and the radius of the Earth is 6.38 103 km.) (a) Assuming a circular orbit, what is the orbital period of this satellite? s (b) What is the satellite's speed in its orbit? m/s (c) What is the minimum energy necessary to place the satellite in orbit, assuming no air friction? J Need Help?
