If one billion people on one side of the planet can be orchestrated to jump up at the same time

[SSSnail]

Assuming they're packed together in a space that can accommodate 1 billion people. Yes, they ate.

Edit: Here are some more variables so some physics dudes to plug them in an equation somewhere.

Assuming average weight is 130 lbs
Assuming each human footprint is 2^ft
Assuming the average height of the jump is 1.2 feet


GOGOGO!

 

[EvilYoda]

What kind of shoes are they wearing?

 

[nerp]

nothing.

ever hear of massive earthquakes? that's a lot more than just some meat moving up and down maybe a foot. You don't feel huge earthquakes on the other side of the world.

 

[sandorski]

2 Billion sore knees?

I'm thinking knocked off Nikes.

But assuming the average weight is 130 lbs per human, that's... a lot of weight.

Resonance cascade. Facehuggers would spawn out your ass and then suck your face into their assholes. It'd be weird, brah.

 

[RoloMather]

That would depend on whether the tanks have unlimited ammo and fuel.

 

[Leros]

The earth would move by an unmeasurable amount. But the mass of the people is way way way way way way way way way way less than the mass of the Earth, so it would very small.

 

[gsethi]

F = ma

m = 130/2.2 = 59.09 Kg x 1,000,000,000 = 59,090,000,000 Kg
a = g = 9.8m/s2
so, F = 9.8 x m = 579,082,000,000 N

Someone double check my work...lol...i am sure someone will find a mistake since this is ATOT....lol

Now the real question is, say we have a teeter totter and OP is on one side of teeter totter and above mentioned 1 billion people jump simultaneously on the other side of the teeter totter...how high will OP fly ? Would love to see that in real life..LOL

F = dp/dt

the actual force experienced will depend on the duration of the impact and the change in momentum

so you're better off assuming something like:

your average person can jump 0.3m
let's stick with 60kg for average mass
let's assume everyone lands with stiff knees, duration of impact is 1ms

F= dp/dt ~~ m (delta v)/(delta t)

for a fall of 0.3m (and negligible drag forces), velocity on impact is:
0.3 = (0.5)*(9.8)*t^2 ---> t = 0.2474s
:: v = 0.2474*9.8 = 2.42 m/s

assume 0 velocity after impact
F = (10^9)*60*(0 - 2.42) / (0.001)
F = -1.452 * 10^14 N.

Bastage..lol...solve the edit for me now here it is:

Finish the math and figure out how far the Earth would move. I did it back in high school physics, but I forget what the result was.

Must be the Asian side of the world.

 

[Newbian]

We would go careening into mars and kill the aliens there. :|

 

[IEC]

People would get bored leading up to it and make "babby"

 

[Skyclad1uhm1]

You also have to take into account that it is not a flat surface, and that those people don't all jump in exactly the same spot.

 

[dennilfloss]

There would be worm sign the likes of which God himself has never seen.

 

[Howard]

Nothing.

 

[Lonyo]

2^ft for the average human footprint? Are you crazy?

That picture on the top right is hilariously racist

We're not freaking sardines, gotta give them room to jump you know. I know they don't all jump from one spot, hence the a constant was given so it can be calculated. How much freaking space do you need? 5^ft? I did say average of 130 lbs per human, not YOUR average of 250 lbs.

 

[FallenHero]

alot of dead ants

 

[Mo0o]

Not that much. Total energy would be 2.11e11 J, less than 1 kiloton of TNT.

 

[AstroManLuca]

If everyone in the U.S. jumped, it would have a greater effect.





















Because everyone in the U.S. is fat. Get it?
