I did not say your wifes bow would launch a 40 lb arrow 32.16 ft. I said that if it was aimed horizontally it would accelerate the 40 lb arrow at 32.16 ft/sec/sec and if it was aimed vertically the arrow would not move at all.
So then in your scenario the draw length has nothing to do with it. Her 25 inch draw bow set at 40 lbs will accelerate the object exactly the same as a 31 inch draw bow will that is also set at 40 lbs. Hmmmm that's an interesting theory you have there
When you say a 40 lb draw don't you mean that the peak force for that bow is 40 pounds
Yes I did but then all 40lb draw bows don't put off the same amount of energy do they? Doesn't cam design and draw legth play major roles in determining the amount of energy produced? Couldn't two 40lb pull bows produce considerably different amounts of energy?
BTW I have been polite and curtious in my posts to you. If you don't agree with what I say that is fine but there is no reason to launch personal attacks.
You answered your own question
I know I may sound a bit know it all "ish" and I appolgize for that but I don't appolize for being educated and knowlegeable in physcis and mechanics.
