A satellite is placed in an elongated elliptical (not circular) orbit around the Earth. At the point in its orbit where it is closest to the Earth, it is a distance of 1.00 × 10^6 m from the surface (not the center) of the Earth, and is moving at a velocity of 5.14 km/s. At the point in its orbit when it is furthest from the Earth it is a distance of 2.00×10^6 m from the surface of the Earth. (Note that the Earth has a mass of 5.97×1024 kg and a radius of 6.37×106 m. )
(a) How fast is the satellite moving when it is at its furthest point from the Earth?
(b) If, at the closest approach to the Earth, the satellite could be deflected so that it had the same velocity as before, but was now traveling directly away from the Earth, how far from the surface of the Earth would it get before it stopped, and then started to fall back to the Earth?
