Method Jumping, fall, anyone able/willing to crunch the numbers ?

'On the other hand, if you stop suddenly from 200 km/hr over a distance of a few centimetres, everything in your body effectively weighs 7,500 times more than normal. Your 1.5 kg brain briefly weighs 10 tonnes. In that brief instant, cells are burst open and blood vessels are torn asunder.'

Not a bad way to die. If you can do it.

Part of an earlier post of mine ': what if someone who weighs 50 kg (120 lbs), body length 1.80 metres/about 6 feet) jumps from 100 metres ? Let's assume things don't go ideal, possibly even the survival instinct may kick in. Let's assume a fall with the body in horizontal position, so that weight is (sort of) divided over the 1.8 metres. 50 kg and 1 meters is not the same as 50 kg and a length of 2 meters.

QUESTION: With what speed would that person fall to earth ? Can anyone do the calculation ? Or an estimate, based on what ?'

I know I studied physics, but that was a very long time ago.

You'd be better off rephrasing your question and asking on Quora. Or just searching on there. They frequently answer questions about how long it takes to fall from a given height, and so on.

Anyway, your mass doesn't affect your free fall speed. What it does affect is air resistance (drag), which is far more complicated to calculate and uses all those other factors you supplied like area, as well as air density. Your free fall speed would give you an upper limit of like 150 km/h. This is very generous, air resistance could affect it by like a third of that. There are calculators online that will calculate free fall speed with air resistance, you just have to look up how to calculate your air resistance so you can plug it in.

You're overthinking it.

Anyway, I realised from what you've quoted that you may have a misconception - it doesn't mean you die in an instant, it just means a bunch of damage is done and your brain is bleeding. You probably would go unconscious, though. You're better off just actually looking up what it's like to jump, because most of that article's info is trivia; what that article is telling you is that it's not instantly lethal though.

And if you're not sure if you can land headfirst, that is also concerning.

I've seen videos it looks peaceful

You're overthinking it.

My only take on jumping is the variables , I've seen a kiwi fail to pull his parachute at 30k feet land on a bush and have a broken leg , I've seen someone in the Bronx through their child out of a 6 story burning building barley a scratch , I've been to a 911 call someone fell 15ft off an overpass dead you get the picture , it's either luck science or destiny I don't know I'd be pretty sure at 150ft on your head on a solid surface would surely be death

The only thing that scares me about jumping is the actual jumping (like, having to force my body to make the jump against survival instinct - otherwise I'm not scared of heights). It seems that if you can pull it off properly, you are not likely to linger in conscious pain. But being able to jump headfirst is pretty important. Arak seems to be looking through a lot of methods to assess them, and if instantaneous death is important to him like the quote implies, he should know that it can take a few mins (probably not conscious ones).

What it does have going for it is that it's pretty certain.

edit: Oh and random stuff breaking my fall like Jai said, but I'd never jump where that would likely be an issue.

I like this method because there is no turning back

Edit his reserve failed which is extremely rare

For sure, you are right about that. There are very few methods that that can be said for.

I think it is a good method. It's typically an impulse method because it requires a lot to overcome the survival instinct, but planning a good site can help alleviate some of the risks.

Oh that's 5 and a half miles straight down their was a god for him or he was just a phenomen not sure how long his initial Shute held him so could be less regardless it was way more then a skyscraper

If I remover my training it's approx max speed free fall at 120 kph v 55 meters a second and he only broke his leg

All I'm saying in this world you could jump off the Empire State Building be mush instant death or just break a leg or even get up without a scratch

I'd say 99% death but I've seen otherwise

Another example I'll give when I was in the military had one of my squad shot in both lower lobes of his lungs had no respiratory issues didn't even feel it was hours before he realized had appropriate medical care and the man never realized didn't even blink

And most bizarrely I've seen a suicidal soldier ( ie private pile ) shoot himself in the head with a sidearm 9mm standard issue it bounced off his cranium and came out in his orbital just below his left eye . He's blind in that eye but took it as a sign and is now a complete follower of Jesus spreading the word

I guess I'm saying it's hard to end your life and maybe just maybe other forces are at play

 

[Arak]

Well, let's see. I'm sure many factors are at play.

But to mention one issue: it matters a lot how a weight (or should I say mass?) of 50 kg hits the ground. Hypothetically, on your feet (I know, knees bend or break etc.) or if you fall flat with your entire weight divided over the surface of your body. For example, 20x30 cm=60cm2, or 40x185=7,400 cm2. If you get that point. Numbers, calculations. Or a bit more than guesses.

I doubt Quora likes these questions ... not when they know what's behind that question ! It would require a lot of rephrasing, and some of it would be lost in the process.

The human body is designed to survive. It can survive a lot. That doesn't mean you won't be terribly injured.

@throwaway123 , that's my prerogative.

I do not believe I would be able to land head first. I like worst case scenario's.

I heard bill burrs helicopter story again today I did laugh but I wonder if that's what you mean?

 

[Arak]

@Jai , No. I don't know that story. But people can survive a lot. Imagine having fallen, your bones splintered/fragmented, tiny fragments fo your skull having penetrated your brains ... yes, you would die (unless you would be able to walk again...) but as usual someone would come along who wanted to 'rescue' you. In absence of that, after months eventually dehydration, starvation, infections, predators would kill you. But that's not the modern world. And I have a medical condition, and I wouldn't want to undergo a certain prescription drug withdrawal ...

 

[Ready to go.]

I can't figure out how to land on my head. It seems you'd have little control over what position your body ends up in falling from a great height. Does anyone know how make sure you land on head?

I'd in my option mate don't have the constitution to jump but if you get hammered drunk or high relive all your wrongs you maybe jump Beachy Head a prime example it's perfect don't know where you live but I feel your fear of it not working and coming out worse but good luck in whatever you decide mate we're on the same side

Just out of curiosity would the drug withdrawal kill you? You don't have to answer

 

[Jai]

I'm sorry it's just weird to me that people who want to die can't those that want to live die , I was in Belfast NI and a fight erupted a strong rugby player got into a fight he did some damage but was drunk someone blind sided him and he fell on concrete smashed his head on the curb died almost immediately

he went out like a man took 6 people on and they was in the wrong he managed to nail 3 of them before being hit by a pint pot and got kicked to the floor

I used to skydive there are variations of a method we call d it the 'bullet ' you do the classic spread then put your arms at your side and straighten your legs and lean back/forward whatever your position is and you plummet at velocity believe me head first
