A golfer hits a ball from an elevated height that is located in a horizontal distance of 180 meter from the hole. The ball takes off with a speed of 40/s at an angle 30o above the horizontal and lands directly in the hole with no bounces (a hole-in-one).
(a) Find the x and y components of the initial velocity?
(b) Estimate how long was the ball in the air?
(c) Find the height, h, of the elevated area above the hole?
(d) Determine the speed of the ball the instant before it lands in the hole?
