A quarterback throws a football at 38 m/s at a certain angle above the horizontal. If it took the ball 6.41 s to reach the top of its path, how long was it in the air?

* I want to say that the formula you use is distance. But im not sure. O r manybe even find out what acceleration was per second.

2 * 6.41 = 12.82 :)
