Max Height of a Projectile

  1. Jun 9, 2009 #1
    1. The problem statement, all variables and given/known data
    Find the max height of a projectile fired at an angle of 30 degrees if it's inital speed is 0.714m/s.
    (this is a lab so I have other data that might be needed)
    2. Relevant equations

    3. The attempt at a solution

    Now this answer is not practical at all. There is no way my projectile went that high. Maybe a couple meters, but not 19.5m. Where did I go wrong?

    Maybe it's your math that isn't practical?

    Shouldn't you get a result that is a small number divided by a big number?

    If v2=0

    then 0=V12-2(9.81)d
