Cool Physics Experiment

Cool experiment where a ball is fired at 60mph from a vehicle moving in the opposite direction at 60mph. We all know what should happen, but it's nice to see it actually happen.

Pretty basic physics. Vector Quantities.

The truck is moving in a positive direction (100km/hr) and the ball is fired in a negative direction (-100km/hr)
If you add the two, you'll get zero. In a perfect world, where there is no slope, wind, and the ball and truck were moving at a perfect 100km/hr, the ball would bounce there, not moving anywhere.
