I am trying to find what velocity and angle of launch is required for a projectile to be fired from the North pole and land somewhere on the equator. I was thinking 45 degrees with muzzle velocity 9401m/s but that sounds ridiculous. Also how much time would it be in the air for?
according to Newtons law since the Earth is flatten in the poles the distance to the center of the Earth is bigger in the equator and therefore its gravity is stronger there.
with this same argument you could say that if you got to the center of the Earth the distance tends to 0 and therefore...
