If you fired a bullet in a desert...

[Carstairs]

Bump: (was an interesting thread, this).

I remembered this thread in the middle of the night when I was reading the Sky News app. The Russian soldiers firing bullets upwards and over the Ukrainian lot. 'So', I thought, 'Where the fuck are those bullet's going to land then?'.
What goes up, must come down, after all.

It's like when those lot in Iraq go bonkers and start firing their guns into the air in celebration. Surely it rains bullets moments later?

Correct, they will all hit the ground after a few seconds but will have lost most of their speed due to air resistance so if it hit you, it might hurt but wouldn't kill you.

The energy in a bullet is proportional to the square of the velocity. An AK-47 muzzle velocity is about 700 m/s. The terminal velocity on its way down due to air resistance would be about 20 m/s so a bullet would have lost 99.9% of its energy by the time it hits the ground.

Would it bounce?

If u fired the bullet and dropped one at the same time from the same height theyd hit the ground at the same time

That's not true.
It's the same as someone saying if you put 2 glasses of water in a -20 degree freezer, one glass containing 10 degree water, the other glass just below boiling point, the hot one would freeze first. It wouldn't. It'd cool down at a faster rate but let's say after 5 minutes, it reaches 10 degrees. In those 5 minutes, what do you think the 10 degree glass has been doing?.....tying it's fucking laces waiting for the other glass to catch up?

Also, if you fired a missile horizontally from the top of Mount Everest, it would carry on going rather than drop to the ground even if it ran out of fuel because it would follow the curvature of the Earth and therefore become a satellite. So whoever tries doing that had better watch out because it could come back round and hit them up the jacksie.

As I understand it... Cooling isn't linear. It's an exponential decay, so I reckon they would reach equilibrium at basically the same time

Boing.

and there were no obstructions for it to hit, would it eventually just make a steady descent to the floor when it loses all its speed? I wonder then if thats the case, if there's anyone stupid enough to stand at the point the bullet lands, and see if the second bullet does the exact same thing.

Its a slow work day today, my friends.

Would the first bullet have some kind of tracking device on it so you could find it in a big fuck off desert.

I've got a small weapon that fires blanks and not very far I have to say but then it's never been tested in a desert.

He should stick to the upskirts pics.
