I asked this on IRC but with only 7 people there, including myself, I'm not too confident I'll get an answer anyway... It seems like such an odd question because you aren't given the bullet's speed. Anyone have any idea what would happen? It is possible that the bullet would push the block, but that just doesn't seem likely at all because of it's speed. Or it could puncture just as deeply, but this time the block moves. But I'm really uncertain about what happens. Any help would be appraicted.
