smart people on funnyjunk (i'm aware that there are very few of you), someone explain to me how a human being can break the sound barrier with no outside assistance. wouldn't air resistance level off his speed eventually?

At the height he will be jumping from, the atmosphere is so thin that air resistance will be lower than an average base jump/skydive. The atmosphere at this altitude is actually so thin that air resistance will almost be negligible. Super sonic speeds are definitely achievable.

If your still curious I suggest you read some stuff found on the Stratos site.

Well it would all depend on how aerodynamic he made himself. It IS possible for a human to break the sound barrier (If you swing a stick very hard and hear the swish, you're doing it) but to do so with ones body...that's very dangerous. He could combust on re-entry, or he could literally be torn to shreds by the pressure.

that's not breaking the sound barrier, you fool. that's the sound of air resistance. the crack of a whip is the sound barrier breaking.

My goodness, you're right. I'm sorry my friend, I just woke up. I was literally reading that after I posted it and I was like "Wait a minute...I'm an idiot, that's not right. Let's hope nobody else notices 0_0".

if my physics are somewhat correct, he could make that speed if added enough weight, but considering meteorites falling from the atmosphere and burning up...this may have the same effect...but as i said i could be wrong. if he does make it with all that equip, he probably going to fall for roughly 15 to 25 minutes.

yeah when air resistance and gravity become equal opposing forces you reach terminal velocity which, for a person is around 125 mph
User avatar #542 to #524 - zarcos (04/21/2012) [-]
Yeah its called terminal velocity, but the air resistance will be significantly less in the stratosphere so it may be possible.....but when he does make it to the denser part of the atmosphere the friction from the air resistance will likely burn him to death....how fun.

maybe he'll break the record for first charred corpse to break the sound barrier.
User avatar #552 to #549 - zarcos (04/21/2012) [-]
lol best record EVER

The higher up you go, the less the air resistance since there is simply less air. Since he's jumping at the stratosphere, there's very little air and so the force of air resistance is quite small. He would accelerate at g to whatever the terminal velocity is at that height, and then slowly deaccelerate as he approached the ground.

If his terminal velocity is higher than the speed of sound 340m/s, he would break the sound barrier.
User avatar #530 to #524 - OuterworldKing (04/21/2012) [-]
He's not going to break it. The sound barrier is 712 mph I think, or close to it. He's only going to go 683. That i believe is the terminal velocity for an average human being. But I could be wrong.
User avatar #534 to #530 - batassassin (04/21/2012) [-]
that's what i'm thinking, he'll reach terminal velocity far before the sound barrier.

are you aware of this thing called gravity?

Are you aware of wind resistance and terminal velocity?

User avatar #536 to #528 - lmaso (04/21/2012) [-]
yes, i think i am.

In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas).

that's fantastic, i'm well aware of that. but he'll reach his terminal velocity far before he hits the speed of sound.
