Well, where are you shooting from?

I assume that the bullet is not going more than 6km/s?

From the ground (yes not over 6km/s). Could you give me answer and explanation ?
Thanks

6km/s is Earth escape velocity. I think you'll find that the problem specifies that the bullet is being shot from the surface of the Earth.

If you shot the bullet straight up out of a moving car, would it come down and hit you? What if the car was turning? What if the someone stomped on the brakes?

Yes the bullet shot from the surface of the Earth and pistol is not moving. So it should fall down in the same spot ,right ?

So, would the bullet move with the Earth after you shot it?

Yes. Conservation of momentum.

Actually, since the Earth is spinning, the reference frame is accelerated, so the bullet would not be moving with the earth.
