wow...the sad thing is i'm tempted to try the stunt with my elbow or body..i'll have to pass on the head...i know i can break 2 15lbs bars of chocolate stacked with my hand...(i'm a confectionist) so i'll have to try the elbow...hehe this should be fun

I do that every morning before i go to work.

Anyways jokes aside , this a post that was made on another forum by a member in wich he did some math on this video check it out:



"Ya seems kinda hoookee to me, so i decided to check some things out scientifically...
2 276 pound-force = 10 124.152 361 6 newton
21 Mph=Speed of His arm
21 mile/hour (mph) = 9.387 84 meter/second

Force (Momentum)= Kg(Mass) x Meter/Second (Velocity)

10124N=Mass(?) x 9.38(m/s)

so for him to generate 10,124Newtons he must mass must be=
10124/9.38=1079.3(KG)
1079.3(Kg)=2374.4 (Lbs)

Obviously he does not weigh over a ton. So where does he generate this force from? Force is simply Mass x Velocity...

Now again when the 275 lb guy hit the bricks and generated 4137 lbs force.
4 137 pound-force = 18 402.292 759 2 newton
How could he even generate more force than a Minivan travelling at 35 mph hitting a brick wall?

Note: The minivan was compared to the guy's elbow power not even a full body contact!

He does not weigh as much as a minivan.
He is not running faster than a minivan.
His bones are not harder than a minivan.
Something is Fucked here"

Whoa so why aren't you guys working for discovery if you can figure this shit out?

yeah, your friend doesn't understand physics too well. His mass doesn't matter, it was his momentum, from which Force is mathematically derived. :D

I see some math has been done there, maybe wrong? care to do some math yourself and show us why its incorrect smart guy?
Ill explain it to you again since i dont think you understand much of anything.This video was posted on another forum and someone on that forum , that i dont personally know, made this calculations.Do you understand this much? I just put this reply here on this thread to see if this calculations are right or wrong.
Now if they are wonrg like you say ,and keep in mynd that i cant prove if they are right or wrong cause i have no expertys in this field , why dont you show me exactly where he got it all wrong?
Lets see if you can do anything else beside posting retarded smart ass comments.
