Momentum = (mass*velocity)/(32.17*7000)
or
(grains arrow weight*fps)/225,190
Kinetic Energy is Mass*Velocity*Velocity/(450,380)
I think these values would mean a lot more if people could post their draw weight, draw length, arrow weight and velocity along with their bow model and arrow selection. There are some really impressive numbers posted here and I'm sure many folks would like the recipe for each of these setups.
Thanks!
