What was the initial velocity of the ball?

[statefanchris]

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 what's the initial velocity?

A ball thrown horizontally will reach the ground in the same amount of time as a ball that was simply dropped from the same height.

There is an animation here: (as well as an explanation)

Its not exactly the same but its so close that its negligable.
