If you fired a rifle at a perfectly horizontal angle (zero degrees), would the bullet travel farther if there was a vacuum?
On one hand you have air resistance slowing the bullets horizontal velocity, which would serve to decrease the total distance traveled, but then at the same time the air beneath the bullet would act as a cushion slowing its vertical descent, which would increase the total distance traveled.
I'm guessing that the bullet would travel farther in a vacuum, because if you take an object moving at supersonic speeds in the X dir and only a small fraction of that speed in the Y dir (falling speed), the force of air resistance is doing much more to slow the bullet down horizontally than vertically. In other words air resistance is hindering the bullet more than it is helping.
Any physicists here care to explain?
