Can't be done, though I'd be glad to if the variables were know, because the math is pretty simple. The problem is that a football, when dropped, thrown or otherwise released, presents a drag coefficient to the atmosphere. In order to calculate the 9.8 meters per second squared until terminal velocity, you have to have the values for that drag coefficient each millisecond. One could argue that that is true until terminal velocity is reached, but that is a specious argument, since terminal velocity is only precise as the ball presents itself to the atmosphere, ie,. a spiral would have a greater terminal velocity than a spinning in a horizontal plane ball. Either way, I'm guessing that it is about 100mph, not much different that a major league fastball, and sighting it would be harder than catching it. Whatever, I'm kind of sick of Gronk. 1

Nextmanup Posted April 26, 2021 Author Posted April 26, 2021 I have no doubt the ball reached terminal velocity, and that it is not an impressively high number. But that isn't what makes the catch impressive IMO. A football is not an ideally designed aerodynamic object and I assume it was just dropped laterally, with no spin. It would almost certainly have been darting and moving around like a knuckle ball on the wind, coming down from the equivalent of a 60 story balcony. I'm surprised Gronk could judge where to be standing and keep up with the jerky movements of the ball in order to catch it, along with whatever speed it was traveling at as well. I'm guessing it was like 60 or 70 mph tops. So not "slow" exactly, but the raw speed is not the impressive part of the catch. 3

I hope he gets layed out by Tre White ala JuJu when Buffalo plays them in the Super Bowl this year.
SlimShady'sSpaceForce Posted April 26, 2021 Posted April 26, 2021 It took 3 tries. He beat the previous record by 35 or so feet.

Jerome007 Posted April 26, 2021 Posted April 26, 2021 Well that's a world record I think I'd have a chance to beat! 1

A human terminal velocity is like 120 mph...I bet a foot ball is way less Update - Terminal velocity football somewhere between 60-70 mph.......so.....the whole thing is BFD Hell, our QB can throw that fast...

Simply time the fall and you'll have the velocity. Dropped from a helicopter I'm neither assuming the football was entirely free falling or the exact distance traveled. Doesn't sound like the event was set up to meet those specifications.
Iiiiiiiiive Got a Feeeelin Posted April 27, 2021 Posted April 27, 2021 He fumbled the first 2. and then caught one from a helicopter? i dont get it. But, yeah man his parents must be sooo proud

MJS Posted April 27, 2021 Posted April 27, 2021 He could probably set another record for surviving a 600 foot drop by landing on his head. 1

On earth, a free object accelerates at 9.8 meters per second squared. Simply time the fall and you'll have the velocity. well you got the first part right. Forgot to take into account wind resistance (drag), which will put a cap on velocity. In a free falling skydiver the terminal velocity is around 160mph, no more acceleration after that. I'd say an american football probably maxxes out around 60mph depending on spin. About as hard as Josh throws his fastball, which is cooking. The hardest part of that catch I think would be the knuckle ball effect when the rotation slows or stops, thats probably why he whiffed on a few (either that or Gronk was drunk, maybe a little of both)
