if rock A is dropped from a cliff and rock B is thrown downward off the cliff, which of the two has a greater velocity?

  • Physics -

    Rock A
    V^2 = Vo^2 + 2g*h.
    V^2 = 0 + 2g*h
    V = Sqrt(2g*h).

    Rock B
    V^2 = Vo^2 + 2g*h.
    V = Sqrt(Vo^2+2g*h).

    The Eq shows that rock B has the highest
    final velocity.
