Homework Help: Ball with vertical motion

  1. Oct 10, 2007 #1
    1. The problem statement, all variables and given/known data
    A ball is thrown stright up with the speed 25m/s
    how high does the ball go?

    2. Relevant equations
    S=v*t or V=vot+at
    I know gravity is a neg acceloration so I should have -9.81 somewhere

    3. The attempt at a solution
    I need to find the time first am guessing so, T=s/v but i dont know S ether just 25m/s and -9.81 I know this is most likly very simple but it just eludes me
