But will the time vary based on velocity of the bullet?

You see? You didn’t answer the question.

No. The horizontal moment has nothing to do with gravitationL attraction


These bozos didn't believe me either until I kicked their asses.

When I was young and learned about orbital mechanics, I found it hard to believe that everything in orbit was falling towards the earth.

Why the objects didn’t hit the earth, that part was really hard to believe

That's mostly true, except for very high powered ones. Turns out they hit a tiny bit later. Because physics

If the earth was actually flat, no matter how high the velocity of a bullet, it would simply fall and hit at the same time as any other bullet, moving or not.

That Physics.

But the earth is not actually flat.

Which is why something can reach "orbital velocity", which means even though it's falling (just like a bullet), it never hits, because the earth isn't flat.

Low earth orbit this is 17,500 miles per hour.

While a 14.5×114mm round fired flat won't even come close to orbit, it does travel far enough that the curve of the earth means it hits slightly later than a bullet just dropped from the same height.

Most people absolutely don't care about this at all. Those that do will now argue why I am wrong.

The question actually isn't as stated below

The real question is how can you, yes you, cause anyone, forget multiple people, how can you get any single person to think critically? To be skeptical? Or to even just consider they might be wrong about one simple thing?

I say it's almost impossible.

Forget "exposure", if you have ever tried, with good faith and the best intentions, to try and school somebody on the internet, you probably know already exactly what I mean.

It's not much different in real life.

I'm not talking about simple practical matters, like why you should use a phillips head instead of a flat head, or what socket set lasts the longest (Craftsman), or how to open a pickle jar.

I'm speaking of contentious and personal matters, or even just scientific ones.

Here is a fact: the Ruger .204 shoots so flat that I can shoot it thru a 100 yard long pvc pipe and not hit the walls.

Do you know what that would do to a fag climatologist? Contemplate that for a moment.

You are right and it happens in every case, not just when some "mystical velocity" is reached (Vm).

The reason is that, because of the curvature of the earth, the ground falls away, as it were, the further from the muzzle the bullet travels.
So while the bullet dropped from your sweaty, inconsequential fingers, covers a distance D, the fired bullet travels D + x, where x is the deviation of the earth's surface from a tangent line (plus height of the muzzle) at the point of firing.

Good show, Robinson. Your ignorance (not meant in the least way as a pejorative) has advanced the understanding of all, and perhaps won a few bar bets.

Any mention of the lack of spherality of the earth or of local geophysical deviations will be rewarded with a hefty sac-kick, thus :De_Bunk:

Arguing/discussing shit on the internet is almost always a huge waste of time

But, sometimes I learn some me things new and valuable from “the enemy”

Especially when it’s a subject I don’t know much about

Most people won’t lift a finger to help you out online, but goddamn, if you are appearing to challenge their pet belief, or worse, something they are an expert in, they will move heaven and earth to prove you are wrong

Many people don’t even know how to do an analysis of facts to form a judgment.

They simply never were taught how. The rational, skeptical, unbiased analysis, or evaluation of factual evidence isn’t even a thing to them. The very idea of self-directed, self-disciplined, self-monitored, and self-corrective thinking just doesn’t exist. Much less rigorous standards of excellence and mindful command of one’s own thinking. Even if one does consider it important, as valuable, using effective communication and problem-solving abilities as well as a commitment to overcome native egocentrism and sociocentrism isn’t something one just acquired by chance.

Hell, if anybody actually reads that above, it probably sounds like nonsense to them

So can I take this as an admission that you're full of crap when you argue? It would save me a lot of time. Or perhaps you could signal when you're trying to be serious.
