Okay I tried for a long time on google and got nothing but statistics about old people breaking their hips and base-jumping. :P
So here's my question, any idea how far the average human is able to "fall" assuming they are able to land on their feet and avoid dehabilitating injury?
Like if I were gonna jump off a tree or out of a window how far would I be relatively safe for?
Is it like some formula like bodyheight x 1.5, a set number or just completely and utterly random and dependant on the circumstances?
Reason I'm asking is I have to give an information speech in one of my classes this semester and decided to do it on how to survive zombie attacks -- I'm looking for a statistic to give about how high of windows or ledges you can jump from as an alternate means of escape.... and teh internet is failing me!1!!!
my vote is for completely and utterly random and dependant on the circumstances.
Ive heard of people breaking a hip falling out of a kitchen chair changing a light bulb, and then people falling off a 2nd storry roof and getting up laughing. But any good stunt man will tell you if you know "how to fall" you can fall a lot more distance without injury.
Maybe you can get some info from that can help you. (click the guy )
edit-mirroring image and cause i just want to keep it myself too :P
Assuming you land well, you can fall distances of up to 10 feet in relative safety.

"The basic rule is simple: 1d6 poitns of damage per 10 feet fallen, to a maxiumum of 20d6. If there character deliberately jumps instead of merely slipping or falling, the damage is the same but the first 1d6 is subdual damage. A successful jump check allows the character to avoid any damage from the first 10 feet."

Of course any actual statistics are still welcome :P
i think it mostly depends on how well you're able to fall. if you absorb the impact over a long period of time, say, by bending your knees as your falling to then rolling down and stuff, the force will be distributed over a length of time. if you just land straight on your leg all of the force goes to your leg at that instant and it snaps. knowing how to fall, and what your falling on have an effect on it a lot.
Your average person can fall about ten feet and walk away if they know how to land. In other words, you could jump out a second-story window and keep on running. Anything higher than that and you won't be able to limp faster than zombies can shamble.
I suggest you work the word "defenestrate" into your speech.
I kept thinking about this and went down the same line, but went with the calculation of force.
F = ma, or Force = mass X acceleration where force would be the impact
freefall acceleration is approximately 32 feet/second[sup79138ea41]2[/sup79138ea41].
so at about 6 stories you hit the ground at about 50mph, OUCH!
On a parachuting site i found this..
parachutists are taught to land on their toes, with their feet together. They keep their knees and hips slightly flexed to absorb the shock at the moment of impact. After impact, they roll onto their calves, thighs, buttocks and back. This manuver allows the impact forces to be mostly distributed through the soft tissues of the joints and muscles, rather than into inelastic bone. Additionally, the rolling manuever spreads the impact forces out over a larger area of the body. It has been demonstrated that just bending the knees during impact can reduce the impact force 36 times
PS hope any of this helps, and how about posting the final report for us here?
It totally depends on the way you fall, as well as body mass/flexability/physical fitness.
I remember reading in an article about 3 months ago of a gymnast in germany falling out of a 4th story window. She stablized herself on the way down, landed on her feet, and only suffered...either a sprained, or broken ankle, I can't remember which.
If you go on ebaums world, or maybe it's kontraband, it has this guy who is working on an electrical box at the top of this building about 15 feet up. Gets electrocuted, and falls all the way down. Gets up perfectly fine.
I've heard of people parachuting, and their chute not opening up, and them only sufferering a couple broken legs.
There's to many factors to really give a definate answer on what height you can survive from.
Owen Hart fell 70-80 feet, and we all know how that turned out... however I don't believe he landed on his feet. :( There's stories of people jumping out of 2 or 3 story windows and escaping serious harm though.
Oh, and I agree that you need to work "defenestration" into your speech at some point.
It probably depends too on certain people and their bone density. Elijah Price wouldn't be able to take a fall from but about a foot or so and he could shatter his leg. David Dunn, on the other hand, could take a good 5 or 6 story dive and walk away perfectly fine.
I would just like to mention that about three years ago someone told me that if you jump off of a table and land barefoot on tiles on your heels instead of the balls of your feet, you'll probably be crippled for life. Since then, every single time I've been barefoot in a room with tiles, I've had this image of myself jumping off of a table and landing on my heels. I always cringe and try to think about something else, but the thought keeps resurfacing.
Senn -- I've got that book in digital format and in paperback.
Also picked up the Zombie Movie Enyclopedia for this project and while its a little outdated (printed just before the first Resident Evil movie came out--so it doesnt have anything on any of the 'new' zombie flicks) its got tons of info on just about everyfrom from 1968-1998
And I'd be more than happy to post what I've got when I'm done here. Its not a report per se though, its a speech. So it won't read like a typical essay would.
(Height in inches x 2.5) + Weight in pounds x .1 = DP (damage potential). 36 would be an average DP for a male of 70 inches (5'10") and 180 pounds.
FF (Fall Factor) is determined by dividing feet fallen into 10 foot segments and then adding them together. Multiply this total by 2.
Example: Falling 30 feet you would add 10 + 20 + 30 = 60 x 2 = 120.
The model assumes falling onto concrete. If you are falling on to something softer you can divice the FF by up to 2 to determine your Final Fall Factor (FFF). Examples: Water 2. Snow 1.5. Grass 1.2.
DP + FFF = Ouch Factor (OF)
Spryness (S) determines how well you can take a fall. Spryness has a default value of 20 modified as follows: +3 if very young. +2 if still athletic. +6 if you "professionally tumble" (Gymnast Airborne etc.). +3 if you take a martial arts class or otherwise jump around a great deal. -3 if showing age. -6 old. -5 to -10 if unprepared for the fall or other bad falling conditions.
Divide Ouch Factor by Spryness and consult the table below.
1: Possible bruising or scrapes.
2: Pain sufficient to cause impairment.
5: Multiple breaks, Trauma and possible unconsciousness.
6-7: Internal damage and multiple fractures.
8-9: Severe trauma. Death likely.
10+: Greater damage and likelihood of death for each extra point.
