First off, thanks for the responce. Kinetic Energy was my first standard and I'm glad to see that echo'd as appropriate. It has been a long time since I've thought through this stuff, and I looked at the momentum formula to cross check myself. I know that momentum would go down with increased...
Let me ask this a different way.
I know the current speed and arrow weights for several models.
Using basic mathmatical priciples I would assume I could use that info to calculate either the Kinetic energy (KE = 1.2mv^2) , or the momentum (MO = mv).
I would further assume that having solved...
Ok, here's the problem. I am evaluating multiple crossbows to predict the changes caused by various arrow weights. The original arrow mass and velocities are available. I input the two formula's: KE = 1/2MV^2 and MO = MV and solve for each, and then use those results with new arrow weights to...
