I watched a very interesting program on the Discovery Chanel I think is worth sharing. "How Fast Is Fast". I found the entire program very interesting however the content regarding NASA's Ames Vertical Gun was extremely interesting. The gun was demonstrated shooting a small 1/8" diameter aluminum BB at a block of marble. This projectile was shot out of the gun at 11,800 mph or 17,307 feet/second. The marble block was pretty much blown into dust fragments on impact by this very small lightweight projectile traveling at this speed. A great example of what projectile velocity is all about.
