Homework Help: Kinematics of a thrown football - Find the path

  1. Oct 20, 2008 #1
    - A quarterback throws a football at 25 m/s at a certain angle above the horizontal. If it took the ball 3.2 s to reach the top of its path, how long was it in the air?

    - I have absolutely no idea how to do this :(

    Re: Velocity

    I could be wrong, but if there is no air resistance, then the ball would stay at the same velocity the entire time...

    >_> Woops. I didn't notice you were asking about the time...
    <_<

    hahhaha I think I know this one. It takes the exact amount of time for the ball to go up and to come down so just 3.2 x 2 I believe. but it sounds a bit too easy....
