I am only trying to find an easy way to find out how fast the arrow went...
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.
This program was meant mostly as an easy way to estimate your arrow speed.
However if you give the program first your 20m/30m sight marks and then your 70m/90m, you can find out how much speed your arrow loses at longer distances. If you fire two shots using the same pin at different distances and measure the arrow drop, you should be able to determine the speed without knowing distance to the eye, non? Dan 21/10/08 : Good calculator however it does not seem to account for decceleration and would only be the average arrow speed from distance one to distance 2, beyond distance 2 your arrow would be constantly deccelerating and thus your extrapolated sight pin settings are slightly off.
Richard is a Computer Vision Researcher, head of the CV team. Thus, everything Richard does is correct, and everything Guy does is “cute” and “a nice attempt”.
This program can calculate your arrow speed, given two previously known sight marks.
David Morrish 23/08/08 : As a new archer, I find the sighting info and arrow speed info very helpful, and have recommended the web site to others. A minor point (very minor) is that in the UK we regularly use distances measured in yards, but sight measurements in cm, so I have to convert the tables to give me data in this mixed format. Steve Brown,archery bowmanship and courtesy 11/11/08 : Hi I read the comments with interest do youhave a similar one for flight shooting.
I am very happy to live with this minor issue, but if you ever found yourself with nothing to do sometime ........!!! Best wishes, David Morrish Harry Marx 03/09/08 : I did the same thing, but derived formula myself. Normally the arrow is shot at 42 to 47 degrees with specialist bows?
It’s a solid division of labor, with one notable exception: Richard.I would like to find out my arrow's speed so I could figure out its foot-pounds of energy. ben 17/06/07 : this formula is all well and good but what arrow weight is it going off?bestel 17/07/07 : Hi Apostolos and congratulations, great job !I'm not in any club and I can shot when I can- which is not very much.I am doing this for my science fair project, and I am soooo confused! what in the world is 'sight mark setting' and 'eye to sight pin'??????

Or its just enought to know the sight difrence between two distance?
