| Let say you are traveling at 1200 fps and shoot a gun, say a .45 with a bullet velocity of 900 fps will the bullet exit the barrel? |
|
yes, add the 2 together and the bullets speed is at a little over 2000fps. but thats not a physics question. Here is a physics question.
now, what if you are traveling at .9 the speed of light in your rocketship, and right as you are coming past earth you turn your headlights on. How fast do I on earth see your light beam traveling? |

How fast do I on earth see your light beam traveling? You would see the light thats traveling at the normal (only(except for medium differences))speed of light. Light does not work like a bullet leaving a barrel does. To answer the OP, the bullet would leave the barrel at 900 fps relative to the gun itself. So you would add these two together to get the total velocity. Now what would happen if you were traveling 1200 fps and shot a bullet at 900 fps directed behind you?

These speeds are all still Newtonian physics, so things like forces and velocities are linearly additive.
The bullet (and the gun and the shooter) are already going 1200fps, the bullet will accelerate another ~900fps (omitting the effects of increased drag due to increased wind resistance at the higher velocity). |
