SURFELITE 10/02/10 : i am also doing a science fare project for my freshman class. can someone post something/someway to help me fine a way to figure out the acceleration,velocity, and speed of a normal pull back tension of the bow a 45lbs.
I found this and thought the very thing I'l just print this out for future questions! Robin Of Locksley 19/06/09 : This calculator is quite vague (even for English standards).If you're interested, contact me : bestel (at) ifrance (dot) com john r 26/07/07 : i used your speed chart and checked it against many of the known sight marks that i have and it was accurate for all of them.im not the greatest archer but found your formula works for me. Apostolos 03/10/07 : Archimedes: you'd better use one of the other calculator that work on principle of draw weight and arrow weight.This would be the most accurate way to determine the speed for the particular setup you're using. Patrick Andresz 17/07/09 : Thank you very much for this nice programm ! Don Walker 22/09/09 : an excellent tool but for one thing! would it be possible to produce a version in Yards and diference in site marks settings in mm for old field archers Mark 25/09/09 : I didn't believe it when I looked at the numbers, as the difference between each 5M distance for time and sight markings seemed to be almost constant.It's very helpfull and so helped me to verifie my estimation of the speed of my arrows. But then thinking about the speed of most compounds (300 fps) this would make sense.
