A satellite revolves around the earth at a height h = 4Re, where Re = 6400 km is the earth’s radius.
(a) Find the speed of the satellite in terms of the earth’s radius and the gravitational acceleration on the
surface of the earth (g0 = 9.8 m/s2).
(b) Calculate the speed of the satellite at the height h = 4Re, by using the formula in part (a).
(c) Calculate the period of the satellite around the earth.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
