At Green Hills golf course, the ninth hole par 3 isfrom an elevated tee box. With a laser rangefinder, a golfermeasures the flag to be 143 m 18.5 degrees below thehorizontal. The golfer uses a 7 iron, which launches the ballat an initial angle of 62.5 degrees above the horizontal.
1. If the ball lands next to the flag, what was the intitialspeed of the ball?
2. What was the maximum height of the ball?
3. What was the speed of the ball at maximum hieght?
4. What was the speed of the ball when it reaches green?
