If you are not familiar with the equations for trajectories, the wikipedia article for that subject has a good treatment. Just plug in your values for the equation of motion, and crank it out.
If you get stuck, come on back with your work so far, and we can give you a nudge in the right direction.
A golf ball is shot from a tee, elevated 20m above the green, with an initial speed of 27m/s at an angle of 50° above horizontal.
a) What will be the speed of the golf ball before it hits the green, 20m below it started?
b) How much time will it take for the ball to travel from the tee, where it is shot to the green?
c) What horizontal distance will the ball travel in moving from the shot at the tee to hitting the green?
