It may not be as cut and dry with just a physics equation. The time I was speaking of I had a deer up hill and about 50yards from me, quartering away and walking up a hill. Since it was walking I went for a safe shot behind the shoulder. The bullet went in behind the shoulder facing and hit the opposite shoulder in the deer. The deer was pushed up\over about 3 feet and landed on its side dead.
Yes the meat in the opposite should was a mess but no suffering involved.

I didnt know the Myth busters were the end all for physics ?'s.
