whats the formula for KE ???
i belive its 1/2 mass times the squared of the speed, am i right??
because if im right, i think that speed would be more important than mass, because the speed is squared and mass is divided.
so, this leads me to think that a lighter, faster arrow would have more KE than a heavy, slower arrow. of course that a heavy and fast arrow would have the most KE. right or wrong??
i have had this questions for some time now, and i think its time someone points me in the right direction.
thanx for your help
