I've been searching all over the web and on this forum for an answer, and I haven't found it (or I may have found it and not understood...). If this is a re-hash, I'm sorry...
I'm working on some ballistics calulations for long range rifle shots. I've got pretty much everything worked out except for the Coriolis Effect. It may have such a small impact it's not worth dealing with, but I need to know. I've never done rotational dynamics like this, so I'm a little out of my element.
I know that the main equation is Fc = -2m(WxV) where F is the end force, m is the mass of the item in movement, W is the angular velocity of the frame of reference, and V is the velocity of the item in movement. That's pretty much all I understand...
Here's my example: I'm sitting at a laditude of 36.728 North and I'm firing a 750 grain 0.510 caliber bullet at 4000 fps straight North. It goes a distance of 1760 yards (one mile) in 2.082 seconds. It's traveling 1607 FPS when it get's there. How many inches has it been pushed off course due to the Coriolis effect (pushed to the right I believe)?
I've read that in the northern hemisphere the pull is always to the right. Is this correct, even if I'm firing Northwest for example? I need to know if I have to adjust for direction of fire as well as longitude...
Thanks.
