I've got a few silly questions...

Let's say you had a large canon powered by compressed air or some other high pressure gas.

If you fired a projectile ( a moon rock ) from the surface of the moon toward Earth, would you be able to create enough force to reach escape velocity?
If so, how long would it take for that projectile to reach Earth?
Would the projectile continue to increase speed after leaving the barrel of the canon or does it stay at the velocity from which it leaves the barrel? If all these things were possible, and you were able to calculate velocity, trajectory, and the entry point into the Earth's atmosphere, would the stones survive the trip through our atmosphere? And/or how large would the projectile have to be to survive atmospheric entry? (I know this is a loaded question, please don't get caught up on this one, the next one is the question I'm really curious about) ;)

And finally...

If the projectile (moon rock) did survive all of this, would it be considered a meteorite?

Scientifically speaking wouldn't this be an interesting experiment?

Send a lander to the moon with a BIG canon and launch some moon rocks dude! ;)
