Math Problem Statement

The tee of the world’s longest par 3 sits atop South Africa’s Hanglip Mountain at 400 m above the green and can only be reached by helicopter. The horizontal distance to the green is 359 m. Let g = 9.8 m/s2. Neglect air resistance and answer the following questions. If a golfer launches a shot that is 28.3 degrees with respect to the horizontal, what initial velocity must she give the ball so that it just reaches the green and how much time does it take the ball to reach the green?

Solve for this time.
