A baseball is thrown vertically upward with an initial velocity of 20m/s. The maximum height gained by the ball is?

I do not understand this problem!

  1. If you have learned about energy, you can calculate by equating kinetic and potential energies assuming all kinetic energy (due to velocity) is converted to potential energy (due to height).
    mgh=(1/2)mv²
    when m cancels out,
    g=acc. due to gravity (m/s/s)
    h=height attained (m)
    v=initial velocity
    final velocity is zero at the highest point.
    h=(1/2)v²/g
