A spacecraft of mass m describes a circular orbit of radius ị around the earth. (a) Show that the additional energy AE that must be imparted to the spacecraft to transfer it to a circular orbit of larger radius r, is GMm(r2 – r¡) ΔΕ= where M is the mass of the earth. (b) Further show that if the transfer from one circular orbit to the other is executed by placing the space- craft on a transitional semielliptic path AB, the amounts of energy AE, and AEg which must be imparted at A and B are, respectively, proportional to r, and r¡: ΔΕΞ ΔΕΔΕ, ΔΕ
