Depends on the speed the ball travels.
In soccer, there is no rule as to how far the ball must travel. The person who starts with the ball could kick it backward, to the person next to them, or down the field.
the more air that is in the ball is how far it will travel, for example a flat ball will not travel as far as a pumped ball. why? because the bounciness of the ball would not be used when it is not pumped however this is not really so as if a ball is pumped up to the point that it is hard it will not travel as far as it would if you released some of the air out of it. every ball that needs air to work has an optimal psi if a ball is pumped to that psi it will travel by far the best than below or above.
As far as he wants
it doesn't matter. a band new soccer ball is as good as an old soccer ball. depending on how much air is in your soccer ball, you'll know how far it will go.
A soccer ball that is more inflated (has more air) tends to be harder and responds more to the pressure applied from a kick. Balls with less air tend to be flatter, and thus not travel as well.
Yes. A flat ball will not go as far when kicked as a ball filled with air.
