A satellite moves around the Earth in a circular orbit of radius r. (Use G for the universal gravitation constant, M for the mass of the Earth, and r, as appropriate, when answering parts (a), (b), and (c) below.)
(b) Suddenly, an explosion breaks the satellite into two pieces, with masses m and 4m. Immediately after the explosion the smaller piece of mass m is stationary with respect to the Earth and falls directly toward the Earth. What is the speed vi of the larger piece immediately after the explosion? (Use G, M, and r, as necessary.)
