Their carcass hits the pavement or any available surface at ~135mph and the same thing happens as when you drop meat from that height with the exception that some of the body parts are under pressure and some of the chemicals might react with that energy to create a larger "meat-impact residual-radius"

In simple terms please.

..you think he had any 2nd thoughts on the way down??..sees the ground getting larger and larger..I wonder if he achieved terminal velocity??...

i can see someone jumping out of a building blacking out, but not having a heart attack. not unless they have a really weak heart.

While we are at it perhaps they die of asphyxiation since they won't STFU and reaslize that their feeble lungs can no longer create an effective vacum to suck air inq

LMFAO! :laugh:

:eek:

Cheers Goosemaster :beer:

Let's see, that's about 2+ jumpers/year. OUCH!!!

You need to redo your math there.

2004 - 1931 = 73 yrs.

31 people / 73 yrs ~ .42 ppl/yr

pwn

v=0
a=9.8 m/s
y= 393.192 meters[Assume "floor to floor" heights are approx. 15ft = 4.572meters -->> 4.572m/flx86fl]


v(f)^2 = v(i)^2 + 2a[y(f)-y(i)]

v(f)^2 = 2(9.8)(393.192)

1 mile = 1.609344kilometers

v(f) = 87.79 m/s = .08779km/s = 316.044km/h= 196mph


The "victim," lets call him Bob, will have reached terminal velocity, due to air resitance and such, before the moment of impact, so he will ahve been traveling at approx. 135mph for some time.


EDIT:

135mph = ~85km/h = 85000m/h = 8500 = 23.61m/s

v(f) = v(i) + at

23.61= (9.8)t

2.41=t



EDITx2:

y=.5(9.8)(2.41)^2

y= 28.5 meters

393.192m -28.5m = 364.692 meters



Finally

y=364.692m
t=?
v(i)= 135mph ~ 60.3504 m/s
v(f)= 135mph ~ 60.3504 m/s
a= 0

y=V(i)t

364.692= 60.3504t


t= 6 seconds

These caluclations lead me to believe that poor Bob was traveling at 135mph for approximately 6 seconds during which he covered 364.692 meters, or approximately 79.8 stories.


yeah, great chocie there Bob.

My favorite part of Yahoo! News is that no matter what the article is, politics always gets pulled into the message board discussion.

O: add this to your post ;)


The "victim," lets call him Bob, will have reached terminal velocity, due to air resitance and such, approximately 2.41 seconds his "leap," according to Yahoo!'s headline.
At this point poor Bob was traveling at 135mph for approximately 6 seconds during which he covered 364.692 meters, or approximately 79.8 stories.


yeah, great chocie there Bob.

An you imagine having a sixth floor office and hearing one hell of a "WHUMP!"

I'd imagine that you'd need some counceling once you found out that the sound you heard was a man exploding like a bag of spaghetti sauce.

A friend of mine works at the ESB, sometimes in the observatory. I gotta find out if he was working when this happened.

I'd like to know what could have been so bad in his life, to want to do something like this? May God have mercy on his soul.:(

Pavement either shears or cracks due to side forces and tension, and crumbles with EXTREME compression.


mass body + 135mph = big fist into concrete, so yes, it will crack and make a nice little crevace, but that is totally different than a dent where the material is actually deformed. In the case of concrete, the bonds totally fail

I think.....

If I were going to off myself, I wouldn't bother going all the way up to the Empire State Building. I would just smoke a stick of dynamite :D

Screw the mess. It's not like I'm gonna care!

assuming the guy weighed 200lbs, that's around 6500 lbs of theoretical force of impact. it wont be all concentrated at one point, so the highest force acting on the concrete would be around 3-4k. thats probably enough to crack the top layer of concrete into cinder block sized chunks.
