  6.   * COMPUTE KINETIC ENERGY
  7.   *_______________________________________________________________
  8.   * This program computes the kinetic energy of a moving object
  9.   * based on its mass and velocity. The program uses a function
  10.   * to calculate and return the kinetic energy.
  11.   *
  12.   * Computation is based on the formula:
  13.   * Kinetic Energy = 0.5 * Mass * Velocity * Velocity
  14.   *_______________________________________________________________
  15.   * INPUT
  16.   *   mass           : Mass of the object in kilograms
  17.   *   velocity       : Velocity of the object in meters per second
  18.   *
  19.   * OUTPUT
  20.   *   energy         : Kinetic energy of the object in joules
  21.   *
