Determining KE
I was wondering if anyone could help me out on the topic of Kinetic Energy. I was trying to find out what my bow has as I have seen it mentioned here quite a bit. I shoot an XI Impulse, 83# draw weight, 28" aluminum arrows.
Thanks Guys.

RE: Determining KE
@83 lbs you should be pretty high, unless you are shooting 2X4's. But you will need to know your FPS & arrow weight. Check out Bow Jackson web page lots of good info their.

RE: Determining KE
Do you know how many fps (feet per second) you shoot? You also need to know the exact grain of you arrows. Figure...
Grain Weight X Velocity X Velocity then divide it by 450,240.
It's easy once you do it a few times...for example
You shoot 375 grain arrow at 275 fps
375 X 275 X 275=28,359,375 divided by 450,240=62.98 foot pounds of kinetic energy.
Hey look everybody I helped somebody! WOOHOO! Good luck!
