A satellite initially is inserted into orbit at a distance r0 = 8800 km from the center of the earth. When it is at a distance r = 18,000 km from the center of the earth, the magnitude of its velocity is v = 7000 m/s. Use conservation of energy to determine its initial velocity v0. The radius of the earth is 6370 km. (See Example 15.9.)
