Velocity when ball hits ground

  1. Sep 30, 2007 #1
    1. The problem statement, all variables and given/known data

    The speed of a ball is v_b= L/t + gt/2 at a height h_b above the ground. What is velocity when ball hits ground?

    2. Relevant equations

    v^2 = v_i^2 + 2gh_b

    3. The attempt at a solution

    Tried v_2 = v_i^2 + sqrt 2gh_b This doesn't work . Any ideas
