    Re: The Arc on Joe's ball.



    How far is Flacco able to throw a football maxed out, stepping into it and everything? I can throw a football 58 yards actually. (though not on the run, haha. Putting my entire everything into it.)

    By the way, I just straight-up don't believe Kyle Boller threw the ball through the uprights from 60 yards out on his knees. Was that supposed to be true?

    Actually, yes. He did it at the combine, in front of coaches.

    PWD, any way you can figure the total distance traveled along the arc of the ball?
    I already calculated it out. Its about 81 yards. See further up

    Is it on video anywhere? Any sources?

    Well if Flacco practiced I'm sure he could too, then. Because there is no doubt Flacco has more velocity and arm strength than Kyle Boller. (and 100 times more accuracy)

    Re: The Arc on Joe's ball.

    Kyle, I got a total arc length of 66.3 yards. And yes Cpt, that is quite different from what you got.

    Cpt, maybe Iím misreading this but it looks like in your calculation of max height attained, you used 22.175m/s which strikes me as a total speed instead of vertical speed. Either way, I did a time step simulation which is a very different analysis than the one you performed though we definitely shouldnít be getting results this different. I could easily have errors in my work as I didnít put a great deal of time into this.

    Iíll give a brief overview of my method
    Drag Force = .5 * density * vel^2 * Reference Area * Coefficient of drag (~.055 for spinning football)
    Y-accel = - Gravity Ė [ Drag * sin(pitch angle) ] / mass_of_football
    X-accel = - [ Drag * cos(pitch angle) ] / mass_of_football
    Y-vel = Y-vel_old + Y-accel * delta_time <- (same format for x, or arc velocity)
    Y-position = y-position_old + (y-vel_old + y-vel)/2 * delta_time <-(same format for x, or arc length)
    These are performed at each successive time step until y position is less than zero (ball hits ground).

    There are some other minor steps and a number of assumptions that Iíve left out.

    I can't find video of it, but I did find this beauty

There was a lot more to it than Moore not being deep enough, but I don't expect to hear many analysts give Flacco or Jones credit because most of them suck at their jobs.
    Roland you've hit the nail on the head. I watched this play over and over [dvr] , frame by frame. You can plainly see when Joe moves up in the pocket, Moore spys Pitta wide open in the middle of the field, he goes towards Pitta and then sees Joe lean back and launch one. He didn't have time to get back to position himself to cover Jones properly. IT WAS A THING OF BEAUTY - Gonz

    This thread needs a gif.
    If it messes up the thread for those with slow connections let me know and I'll take it off.

    Oops...I see someone else already did a really nice job on the physics.

    I've read through three pages of math and have yet to find one person that would get more than a 65 on the test. lol.

    I sucked at Calculus, Physics and never took statistics, so I guess I'm up a creek too. lol.
