Homework Help: How high does the ball rise before falling?

  1. Sep 21, 2011 #1
    1. The problem statement, all variables and given/known data
    A ball is thrown straight up. If its initial velocity is 24m/s, how high does it rise before it begins falling down?

    2. Relevant equations

    3. The attempt at a solution
    This one is very frustrating to me. My teacher doesn't teach us, he just gives us the homework and formulas. Please help!

    So what formulas do you have that you think might be relevant?
