If you fired a rifle off the back of a train that is traveling at the speed of the exiting bullet, what would the bullet do?
Happy Thursday :) |

Well, assuming you could stand on the back of the train that is going as fast as a speeding bullet and not die, the answer is simple.
The train is going one direction, the bullet is going the other (since you have fired it off the back), no issues here.
Except that train will derail for going so fast |

Agreed. Tim needs to clarify if the shot is fired in the opposite direction the trains movement. I believe the question might be if you fired it in the same direction what would happen... |

| It would be fired in the opposite direction, as if you were standing at the back of the train and fired the gun opposite to the direction of travel. |

Ok... stand by the first answer then. Bullet would travel in the opposite direction at whatever fps it was designed. Regardless of the forward speed of the train the bullet is starting from 0 at the point which it was fired. |

The answer is the sum of two equal and opposite velocity vectors referenced to mother earth. Or you can use another reference if you prefer, eg. the train.
In that case there is only one velocity vector involved.

| As soon as the bullet left the barrel of the rifle, it would drop straight to the ground. |

| Forget about the bullet, buy the stock of the company that makes the train. At that speed it should do very well. |

AND if the wind is blowing in the same direction of the train, that bullet may just backfire at the shooter!:1: |
