AI Thread Summary
Foot contact time with a football during a punt is estimated to be between a quarter and half a second, based on elasticity theory. A former punter recalls seeing images of a field goal kicker demonstrating foot compression into the ball, but specific resources or videos are lacking. The discussion highlights that contact time in a punt is shorter than in a field goal kick. Accurate measurements of contact time are difficult to find, and visual resources would be beneficial for better understanding. Overall, the need for more detailed studies or visual aids on foot contact time in football is emphasized.

Does anyone have resources for how long a foot is in contact with a football. Numbers I have found, but video or set of pictures with time on it would help.

Please and thank you.

Actually real contact time can only be given by the theory of elasticity.
 
Well I was punter in high school, and I'm guessing it's around a fourth of a second during a punt. But that's just a guess.
 
I remember seeing a set of photos of a field goal kicker. It showed the foot compressing into the football to about the center of the football (about 1/2 it's diameter). I can't find the site, and I don't know the duration of this.
 
All I could figure out about it is that the football will contact in a punt less than in a field goal. But I am pretty sure for a punt it would have to be between a quarter of a second and a half a second, any more than that and the football will not pop up into the air and it would take more energy to get it in the air.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
