(I) A space shuttle releases a satellite into a circular orbit780 km above the Earth. How fast must the shuttle bemoving (relative to Earth’s center) when the release occurs?
14–83. A rocket of mass m is fired vertically from the surface
of the earth, i.e., atr = r. Assuming that no mass is lost as it
travels upward, determine the work it must do against gravity
to reach a distance n. The force of gravity is F = GM,m/²
(Eq. 13–1), where M is the mass of the earth and r the distance
between the rocket and the center of the earth.
