Homework Help: Ball throws upward, find maximum height

  1. Apr 19, 2009 #1
    1. The problem statement, all variables and given/known data
    You throw a ball directly upward giving the ball an initial velocity of 10m/s. Neglecting friction, what would be the maximum height of the ball? (Explain why you do not need to know the mass of the ball)

    2. Relevant equations
    not sure

    3. The attempt at a solution
    vi=10m/s d=?
    not much of an attempt, i know

    The ball has an initial kinetic energy, which is transformed into an increase in gravitational potential energy.

    Max height occurs when vy equals zero.

    so if v1 = 10 m/s , think wut would the speed be at maximum height , and remember there is always the acceleration of gravity [ down ] acting on all object thrown upward!
