  6.   * COMPUTE FALLING DISTANCE
  7.   *_______________________________________________________________
  8.   * This program computes the distance an object falls due to
  9.   * gravity. It uses a function to calculate the distance for
  10.   * each second from 1 through 10.
  11.   *
  12.   * Computation is based on the formula:
  13.   * Distance = 0.5 * Gravity * Time * Time
  14.   * Gravity = 9.8 meters per second squared
  15.   *_______________________________________________________________
  16.   * INPUT
  17.   *   time       : Time the object has been falling in seconds
  18.   *
  19.   * OUTPUT
  20.   *   distance   : Distance the object falls in meters
  21.   *
