Deriving Equations - Freefall, Velocity

  1. Sep 24, 2009 #1
    1. The problem statement, all variables and given/known data

    Given a Height of release (d) and the Total time (T) form hand to floor. Derive general equations for vi, vf, h (in terms of d, T, and g)

    vi = velocity ball leaves hand
    vf = velocity of the ball the instant before it strikes the ground
    h = height of the ceiling


    known
    height of ceiling = 9.67 meters [including height of release]
    height of release = 1.58 meters
    velocity ball leaves hand = 12.59 m/s
    velocity ball hits floor = 13.77 m/s
    time it would take to fall from ceiling to floor = 1.41 seconds



    2. Relevant equations



    3. The attempt at a solution

    Just confused at how to start deriving this..
