Dumb Question

[Oldguy]

Is there a rule of thumb formula for rough estimates of the speed of your arrow at impact?

The Easton arrow selection program to calculate KE requires the impact velocity. Well I am assuming (bad thing to do) that IBO is the speed measured very close to leaving the bow. I'm suspect some of you folks have some way of estimating impact speed.[8D]

If you go to http://www.bowhuntinginfo.com/Kineti...Calculator.htm , it takes you directly to a KE that does not need the impact velocity. All you will need there is total arrow weight and speed of your arrow.

The problem with the above formula is that it gives ke at the bow and not at the target.


As far as a rule of thumb as to how much speed loss you can expect.I doubt their is one because of all the variables that exist in downrange velocity.


That being said,there are programs that will figure in most all the variables and give you downrange velocity and ke.Archers advantage is the one I use and it works great.

I did not know that. Appreciate the info. Learn something new everyday.

The amount of Kinetic energy at the target depends on on far the target is away. The Archey progam will calculate the velocity and KE out to 150 yards if you want. The farther away the target is the less you got..

Go here. It will give you your drop, speed, kinetic energy, and momentum out to 100 yards. Plus it's free.
