I don't know how it`s possible that a cannonball could have enough momentum to travel that far, rip through a concrete wall, then through a WHOLE HOUSE, off someone`s roof, bounce across the road, and through a minivan. WTF did they load that thing with? Uranium?
A full size cannonball at 1000fps has about as much kinetic energy as a car travelling at 95 mph. But the force of impact would be over a far smaller area (so far higher pressure) and the ball is far more solid than the car.
Numbers, so you can see I`m not just pulling it out of the air:
1000fps = 304.8 m/s Mass of ball = 42 lbs = ~19Kg.

traveling at 1000f/ps a 2kg cannon ball would weigh 600kg..
kg is a unit of mass, not weight. So what did you actually mean? 1000fps is nowhere near close enough for relatavistic effects to be of any relevance, so the 2Kg ball will still have a mass of 2Kg.
The equivalent of a 600Kg ball dropped 1m in average Earth gravity, maybe?

You can't get rid of MythBusters! You already took away NASA, what else will keep the generations to come interested in science?
