How do I calculate the initial velocity of a ball if i've only given a maximum height of 12metres above its starting point?

  • Physical Sciences -

    If H=12 m is as high as it rises, the potential energy there must equal the initial kinetic energy

    M g H = (1/2) M V^2
    M cancels out, so
    V = sqrt(2 g H)

    g is the acceleration of gravity
