Answer»

Correct choice is (b) Fall back

Best EXPLANATION: If a satellite were launched vertically from the earth and then released, it would fall back to earth because of gravity. For the satellite to go into orbit around the earth, it MUST have some FORWARD motion. For that reason, when the satellite is launched, it is given both VERTICAL and forward motion.
