    the question: Someone throws a ball horizontally from the top of a 25.0 m high cliff and the ball lands 45.0 m from the base of the cliff

    A) What was the initial velocity of the ball?
    B) What was its speed wen it hit the ground?

    I don't need complete work just a beginning please.

    Use the kinematics equations to solve the problem. If its starting from rest whats the initial velocity?
