In this clip from Mythbusters, the team demonstrates what happens when you fire a ball out of a cannon that is traveling the opposing way, but at the same velocity. If you think about it, it’s pretty obvious. But however strong your logic (or even your mathematics and understanding of physics) is, it still doesn’t quite seem right when you see it through a high-speed camera.
Next time, we want to see a bullet being fired from a rocket car.
