  3. * FUNCTION COMPUTE THE MOVING OBJECT’S KINETIC ENERGY.

  5. * _____________________________________________________________ 
  6.  
  7. * The program uses user-inputted mass and velocity to calculate 
  8. * kinetic energy functions “kineticEnergy”, then displays the result. 
  9. * 
  10. * Computation is based on the formula: 
  11. * 
  12. * KE = 1/2 * m * v^2 
  13.  
  14. * Where: 
  15. *       KE = Kinetic energy in Joules 
  16. *       m = Mass in kilograms 
  17. *       v = Velocity in meters per second 
  18. * ____________________________________________________________ 
  19.  
  20. * INPUT 
  21. *   mass             double    Mass of the object in kilograms 
  22. *   velocity         double    of the object in m/s 
  23. * 
  24. * OUTPUT 
  25. *   mass             double    Mass of the object in kilograms 
  26. *   velocity         double    of the object in m/s 
  27. *   KE               double    Calculated kinetic energy in Joules
