Got a physics question
If you're in some jet car going 1200fps forwards and you shoot a 1200fps bullet backwards, would the bullet just drop straight down from an observer's view? Let's say there's no other force acting on the bullet besides gravity after it gets fired.

I tried that once when I found my X-Wifes boyfriend. It didn't hit him, (maybe it dropped straight down) but it sure scared the S*** out of him.

![]() Why were you looking for your Xwife's boyfriend at 1200fps? I estimate that at between 800 and 900 miles an hour. If, somebody shoots at me, mine drops straight down too. ![]()

I believe the bullet would travel at a reduced speed but not fall straight down as you are also moving foward. Get in the back of someones truck go 30-40mph and pitch a baseball, same effect ball will travel away from the vehicle until it hits the ground.

As reasonable as it may sound that the bullet will exit the gun and "come to a dead stop", this is impossible with no other forces acting on it. If you happen to aim accurately at someone behind you while you travel at this speed. They will be shot....and shocked..... that you are that steady at that speed. Our Earth is turning at an incredible speed, and basically turning in the direction of west toward east. Does the bullet go slower when we aim toward the east? But that brings up another question. If the earth spins basically from west toward the east, why do storm systems and clouds basically travel from west toward east? Looks like the earth would spin and the clouds would be stationary above the earth, and appear to travel from east toward west. I need beer.

are you taking in account the low and high pressure areas behind the car that would be created at that kind of speed?

Air resistance is relative to the object in motion and velocity. There will be air relative to both objects, so impact will occur at the same time. As the slow moving bullet from your hand is affected by the air, the one from the pistol is being affected by air at a rate relative to the velocity it is traveling through the air.
