    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"

    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.
