[SOLVED] Projectiles, spin, momentum, and range
Greetings. I am simply seeking information regarding the matters of the subject line.
Here is the situation:
A spherical projectile (6mm pellet) is fired out of a device at say 400 feet per second. It is fired out level to the ground (as if you are aiming a gun at a target - no real trajectory above horizontal).
To complicate things, a backspin is placed on the projectile inside of the barrel... the backspin causing a change in pressure above the pellet as it spins, thus to some degree counteracting gravity.
So if I were to speculate on the different ranges (distances the pellet would travel before hitting the ground) of a pellet fired at 250 feet per second vs. one fired at 500 fps, what all would come into play?
Thanks for any input.
