t.r.k. said: (quoted from post at 00:38:49 12/16/14) Its the Mass of the steel, not its velocity that stuck it in the tree like that. 125 lb. of anything does not stop on a dime.
I recall seeing a demonstration once between a 22 cal. bullet and an arrow. Fired both into a coffe can full of sand. The 22 bullet went about 1/2 way through. muzzle velocity was something over 300 fps. The arrow with a much lower velocity plowed all the way through. But it weighed much more than the bullet.
I wonder how fast the car was going?
Sectional density is the term you're seeking. Something short and fat has way less SD than something long and thin, both weighing the same. A 150 gr 45 cal bullet has way less SD than a 150gr 264 cal bullet.
ETA, sorry Mark, I didn't see your post.
