Trajectory of a ball

  1. Aug 31, 2015 #1
    1. The problem statement, all variables and given/known data
    Determine the time it takes for the ball tor each the plane of the fence. Answer in units of s.

    2. Relevant equations
    Vf+vi+at
    d=vit+.5at^2
    vf^2=vi^2+2ad

    3. The attempt at a solution

    I found Vix to be 11.59 using trig. I then used the second equation to find time as 1.725. However, this answer wasn't correct.

    What am I doing wrong? Any suggestions on different ways to do this?

    Kind of hard to say what you are doing wrong since you didn't post any work. Also, your picture is upside down.
