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.
The only thing I stepped in was the truth....Sure if the xbow shot the same drag coef, same weight, same fletch, they would hit with the same KE but you want to leave out the power stroke and the fact they don't shoot the same. Thats very important.
In the real world with real hunting equipment the KE in similar because the xbow is more pounds of weight with a short stroke and the bow has a long stroke with less weight. You know as well as I do the bow has a slight better downrange energy because of this. Also the shorter arrow is harder to steer at the longer range.
Why is it the speed bows have a short brace. I bet you know...come on. They store more energy because the arrow stays on the string longer.
Why is it you only want to tell part of the facts....?? You are too embarrassed to admit I'm 100 % right. Now one again show me how the xbow is so much better at along range over the compound.
I hope it's not too late to get your money back from your engineering class.
