The amount of acceleration the book would have to acquire to reach the speed of the bullet, thus preventing it from being penetrated, would be too high. Looked at another way, the bullet's lost momentum would not be compensated for by the momentum needed by the book, yet the bullet's kinetic energy needs to be dissipated as it comes to rest. Smashing it's way into the book would rupture molecular bonds and the energy would 'surface' as heat.Unknownhttps://www.blogger.com/profile/10203273170727797853noreply@blogger.comtag:blogger.com,1999:blog-15868947.post-1162625818058933272006-11-03T23:36:00.000-08:002006-11-03T23:36:00.000-08:00The Box O' Truth did a field test on this.TK<A HREF="http://www.theboxotruth.com/docs/bot31.htm" REL="nofollow">The Box O' Truth</A> did a field test on this.<BR/><BR/>TKpecuniumhttps://www.blogger.com/profile/00932887887661968355noreply@blogger.comtag:blogger.com,1999:blog-15868947.post-1162585371612343272006-11-03T12:22:00.000-08:002006-11-03T12:22:00.000-08:00I am pretty sure the force from bullets would just...I am pretty sure the force from bullets would just knock those books over, rather than penetrating them.

Perhaps with my quick hands and martial arts training I can use these textbooks to defend myself from knives and baseball bats.
