Physics

A golfer hits a ball from the origin with an initial speed of 35 m/s at an angle of 44 degrees above the horizontal axis. The ball is moving down when it lands on a green that is 3.00 m above the level where it was struck. Neglect air resistance.
1. How long is the ball in the air ? I know that the answer is "between 3.0 and 5.0 sec" but I don't know how this answer was achieved. How do I solve to get it?
2. How far as the ball traveled in the horizontal direction when it lands? The answer is "between 100 and 150 m" but again I don't know how to solve to get the answer.
3. At the highest point in the path, the ball's speed is:_____ The answer is "between 15 and 30 m/s"
4. What is the speed of the ball 1.8 seconds after it has been hit? The answer is "more than 25 m/s"
