The hammer throw is a very cool Olympic sport. You take this hammer deal and you swing that puppy around your head a couple of times to generate momentum, then let 'er fly. It's all based on this equation ...
D = v02 / g cos ¥ (¥sin2 ¥ 2gh0 / v0 2) ± C [m] (1)
Where "D" equals the distance thrown (m) and "vo" equals the velocity of the hammer at the moment of release and "ao" equals the angle of release and "ho" equals the height of release and "g" equals the acceleration of the Earth and "C" equals the influence of air resistance. Points are awarded for "D". I only mention this because it's fun with cats, too.
