5 km/sec is anything but low velocity. The fastest velocity listed on this chart of military ammunitions is 4000 feet/sec (at 78 feet from the muzzle, but initial velocity is probably not too far off from that) which is around 1.2 km/sec. 5 km/sec is 4 times faster than a speeding, armor piercing bullet. Any object traveling anywhere close to 5 km/sec (wherther composed of rock, ice, or pure crystallized aspartame) is going to make what is known in technical terms as a "giant-ass" explosion, excavating a deep, round crater. Here's an amazing bit of video that I've been itching for an excuse to post: http://www.youtube.com/watch?v=QfDoQwIAaXg&feature=player_embedded ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
