A ball is thrown horizontally from a platform so that the initial height of the ball is 6.0 m above the level ground below. The ball lands 24 m from its original horizontal location. Find how fast the ball was thrown.
Show work i just don't understand

  • Physics -

    d = Vo*t + 0.5g*t^2 = 6 m.
    0 + 4.9t^2 = 6,
    t^2 = 1.22,
    Tf = 1.11 s. = Fall time or time in flight.

    Dx = Vo*Tf = 24 m,
    Vo*1.11 = 24,
    Vo = 21.7 m/s.
