If you are on a train that is moving at a constant speed, no turns, no bumps, no air resistance; and you have a gun. The train let's say moves at 1000 mph and the gun shoots the bullet at 1000 mph, if you shoot the bullet off the back of the train, won't the bullet be moving at 2000 mph in respect to an observer on the ground? Similarly if you are at the front, won't the bullet be traveling as well at 2000 mph in respect to an observer on the ground?
