RE: Who said that physics wasn't fun?
That is pretty good penetration Bow Hunter44. I do agree that momentum should deffinetly be refered to more than it is, all you ever hear about is KE. Dont get me wrong it takes both to do the job. I just think people are stuck back 20 years ago when you had to shoot a big old honkin lincoln log of an arrow to get penetration because the bows were so slow. The speed makes up for lack of mass to an extent, so why do people still act like shooting a lighter arrow is emoral or somthing.
