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?
According to James Gunn, Kurt Russell was de-aged for the film's opening flashback (set in the 1980s) by visual effects company Lola VFX, in what was a "long, painstaking process that took many, many months to accomplish." He continued, "I know Lola did Michael Douglas, and I think they did Tony Stark and Steve Rogers as well.
They're the best at what they do, and keep getting better." See more » Unlike the iconic Walkman and headphones, the headphones used with the Zune are not original Zune headphones.
It can also compute your other sight marks for FITA and other distances. have a good day pb Joe Tapley: Simple and pretty accurate - well done. PS: Joe, you drift program is excellent, it's amazing how good a model of arrow flight you made. Can it be tweaked to allow for sight marks where the distance between the eye and the sight pin changes (ie. ) Apostolos 20/05/07 : I think it could be tweaked for that but I have to find that piece of paper that I had all the equations written on..
Perriswood Dick 30/03/07 : I can see how the algorithm accounts for different arrow size/weight but where is limb/r1ser length and draw weight taken into account RLH Apostolos 01/04/07 : In fact, we don't care about the draw weight but only for the angle difference between the two distances. I was also thinking of doing another version that could calculate your arrow speed loss per meter given all of your sightmarks. Could you please help me figure out how to measure speed of an arrow (point blank) just with draw weight (45 lbs) and arrow weight (385 gr)?
As Steve Rogers struggles to embrace his role in the modern world, he teams up with a fellow Avenger and S. Along the way, old foes turn to allies and betrayal is blooming.
And the Guardians find that they are up against a devastating new menace who is out to rule the galaxy.Or its just enought to know the sight difrence between two distance?and do you thing to make this calculator for windows or windows mobile? Dick Baugh 08/06/08 : I use Accurate Sights software from someone in Australia.It also includes compensation for aerodynamic drag. Dick Baugh 10/06/08 : Comparison with Accurate Sights software: Matched at 20 and 70 yards.Yours is 4.2 inches low at 10 yards, 8.3 inches high at 50 yards and 44.7 inches low at 80 yards relative to Accurate Sights which includes air drag and distance from eye to arrow. The aerodynamic drag is not taken into account as it impossible to do with only 4 inputs.The witty humor associated to charismatic characters and cameo of famous actors make "Guardians of the Galaxy Vol. There are several scenes in the credit; therefore the viewer musts wait until the very end.
