15-113. An earth satellite of mass 700 kg is launched into a free-flight trajectory about the earth with an initial speed of va = 10 km/s when the distance from the center of the earth is ra = 15 Mm. If the launch angle at this position is dA = 70°, determine the speed vg of the satellite and its closest distance rg from the center of the earth. The earth has a mass M. = 5.976(10²4) kg. Hint: Under these conditions, the satellite is subjected only to the earth's gravitational force, F = GM ¸m,/r, Eq. 13–1. For part of the solution, use the conservation of energy. в TA
