Ok, bigboy, you stepped in it. Yes, you are right about stroke, but forgot most arrowguns are 150-200lbs in that stroke. Hense the reason 350fps is possible with some of them. You will never see too many compounds 150lb of draw. I have shot warbows 130lbs at 32". But not the norm for hunting.
If both have the same drag coef, same wieght, same fletch, both will hit the target with the exact KE at thier target. I can prove it with whatever dynamics/statics book you wish. You just showed your hand. Thank you. You know the university in Louisville is an ok school. I highly suggest you don't miss admissions for the fall calculus classes.
No, a heavy arrow does not store up more energy. KE is the square of velocity. A bow can only store so much energy. Light or heavy, it remains the same. Only exception to this is a bow is more efficient with heavier arrows.
What increase is momentum. Look it up. Momentum is weight dominated equation where KE is velocity dominated. Momentum is not energy, and energy is not momentum. How have you gotten thru life this far

They may have similar kinetic but in the end the bow wins out over the longer range. Thats also why you use a heavy arrow out of you slow bow and can still get pass through. A heavy arrow stores more energy with the longer power stroke....you happy with that....???
