Scientific Question!!?

Question

I alex rodriguez hits a ball into the stand and everyone all at once exhaled throught their mouth at exactly the same time, will the ball float back into the pitch?

Answer 1

No, with gravity and the weight of a ball, the breath thing would only work if you could center it into a ft circle 'ray'. With everyone doing it, it would be too diffuse and not work.

Answer 2

Well, people are seated in all directions of the ball, so everyone's breath would pretty much cancel each other out. But, even if everyone breathed on only one side of the stadium, it would be nothing compared to the slightest breeze that could affect the ball.

It definitely won't float back. You can hit a ball into some pretty fierce winds and it won't go backwards.

Answer 3

I would think it would be slowed, but not float all the way back.

The ball would still have enough resistance to keep going forward, but would be affected by the wall or air.

Also they'd have to blow for a long time to get it to be blown that far back...How much blowing power can that wall of air have.


I suppose if you wanted to be scientific, you could calculate the average volume and force of air expelled by a person's breath.

Multiple that by the number of people in the stands and the length, width and height of the stand, to calculate the size and force of air.

The the wind resistance, and speed of the ball, angle, is ball spinning etc. also matters.

How far it moves back depends on air - ball force foward.

Answer 4

Well...hm the air becomes denser, thus little pressure around the "flying" ball. Remember too, gravity vector will contribute to downward weight of the ball... i think the momentum around Alex's ball wil reduce. No it won't float back

Answer 5

I don't think so.

Answer 6

no
