Re: The Arc on Joe's ball.
This was exactly my assessment of it. Moore was the goat, but I think he wouldn't have been the only one, in a similar situation, to make the same mistake. That ball just never seemed to lose trajectory. Sorta like a ball that keeps carrying over a centerfielders head.

Re: The Arc on Joe's ball.
It was a perfect throw. All the kvetching about Moore misplaying the ball ignores that Jones misplayed it as well. I mentioned it on another thread.
Jones turns his body so he's facing the defender, which would have given Moore a chance to get his arm in there if he'd played Jones instead of trying to play the ball. I don't blame Jones- I don't know that he's capable of making the over-the-shoulder catch like we saw Boldin do against the Irsays- but it is what it is. The way Flacco threw that ball, if Jones plays it right the only chance either DB has of stopping the catch is to interfere with Jones. That ball nearly dropped straight down into his arms. That's awful tough to defend.
If there's another QB in the league capable of making that throw, I haven't seen him do it.

Re: The Arc on Joe's ball.
Ran a couple of calculations. Using 3.2 seconds as the hang time (which is what I calculated with a stop watch, but someone else just verified) and the 59 yards traveled estimate, I calculated an initial velocity of the throw at 23.02 meters/second (which is roughly 52 mph). Using that, I got a 42.92 degree launch angle. Also, the peak height came out to be 12.5 meters (13.7 yards).
If anyone has any theories as to how to use these numbers to get a distance of a curve, feel free. I have no idea.Last edited by dandrews; 01-14-2013 at 02:11 PM. Reason: F'd up some of my calculations

Re: The Arc on Joe's ball.
Haha it only takes pre-Algebra to calculate. Just draw a triangle from where Flacco was when he threw the ball, to where Jacoby was when he caught the ball, and then draw a straight line back to where Flacco was when he threw it, and then finish connecting the dot. Then just do the Pythagorean theorem.
But it will be hard because it's hard to determine how many yards the ball sailed to the right.
EDIT: Oh, you mean including height and stuff. Oops.Last edited by PurpleApocalypse37; 01-14-2013 at 02:23 PM.

This is the greatest and funniest thread I have ever seen. Love it.

Re: The Arc on Joe's ball.
I estimated the distance to the right as the distance from the hash to the sideline (the ball was thrown from and caught within a yard of two of each). Knowing that the has marks are 18.5 feet apart and the width of the field is just over 53 yards (2x+18.5=160), I estimated the short leg of the right triangle to be 24 yards. That's what gave me the 59 yards total.
Long days and pleasant nights.

Didn't the Ravens hire a numbers guru. Maybe he could chime in.

Re: The Arc on Joe's ball.
So assuming the vertical displacement is negligible, we have a distance traveled of 49 meters in a time of 3.2 seconds.
We can calculate vertical velocity by using
0 = (initial velocity)(3.2) + 1/2 ( -9.8) (3.2^2)
This comes out to an initial vertical velocity of 15.68 m/s
We can then approximate max height using
0 = 15.68^2 - 2 (-9.8)(max height)
This gives us a max height of ~ 12.544 meters or about 36 feet
Initial horizontal velocity can be calculated using
49 = x(3.2) + 1/2* -.1 * (3.2^2)
This gives us an initial horizontal velocity of approximately 15.475 m/s
Using the calculated stuff here, we can use the following:
Integral from 0 to 3.2 of
sqrt((15.47 - .1t)^2 + (15.68 - 9.8t)^2)
Which gives us an arc length of 74.551 meters, or approximately 81 yards.
Pretty awesome. Note these are rough figures, since we can't really be completely precise with the information we haveLast edited by CptJesus; 01-15-2013 at 04:43 PM. Reason: Messed up integral

BaltimoreBoy - Do yourself a favor and email that to ESPN/sports science with emphasis on whether Moore could have made that play. That would be a sweet segment and I can't recall an episode where they focused on ball distance / height.
