## Homework Statement

I know this is a basic question but this is my first physics course ever and I am having big time trouble, any help is appreciated!

Chipping from the rough, a golfer sends the ball over a 3.00 m high tree that is 14.0 m away. The ball lands at the same level from which it was struck after traveling a horizontal distance of 17.8 m - on the green of course! (A) If the ball left the club 54.0 degree angle above the horizontal and landed on the green 2.24 s later, what was its initial speed? (B) How high was the ball when it passed over the tree?

I have found tons of examples but they seem to ALL have the initial velocity as a given, and I think I have thoroughly confused myself with so many equations today.
