Hey /sci/, if you shoot a gun out of a moving car, would the bullet travel faster if you're shooting ahead of the car or behind the car. Wind resistance included.

Faster relative to what?

Relative to the ground, the bullet would be traveling faster if you shot it forward.

Relative to you, the bullet would be slow down quicker if you shot it forward, due to increased wind resistance.

If you shoot ahead the wind will push the bullet to a side - same effect if you shoot behind, though thrust behind the car has shaken up the wind, so the bullet travel faster... The wind turbelence from the car will circle around behind the car, and will make the bullet travel to a random location - meaning there will be no point in aiming really.

newtonian physics says that you sum the vectors of force when trying to find the net force acting on an object. the bullet will travel nearly x mph faster if you fire it forward that if you fire it out of the back of the of the car. x is the speed of the car in mph. the actual increase may a bit less than x because the bullet may incur more air resistance due to it's increased speed. in the end though, it doesn't really matter; bullets still fly fast as fuck.
