Determining KE

[Bionicrooster]

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.

@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.

Good judgment comes from years of bad judgment.

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!

Thanks guys! I knew I could count on you.

My KE is 69.65 ft pounds, and my next question is, is that good?

Oh, and AB, bowjackson is a great site, thanks.
