A golfer encounters two different situations on different holes. On the second hole they are 150 m from the green and want to hit the ball 90 m and let it run onto the green. They angle the shot low to the ground at 30° to the horizontal to let the ball roll after impact. On the fourth hole they are 120 m from the green and want to let the ball drop with a minimum amount of rolling after impact. Here, they angle the shot at 60° to the horizontal to minimize rolling after impact. Both shots are hit and impacted on a level surface. a. What is the initial speed of the ball at the second hole? b. What is the initial speed of the ball at the fourth hole? C. Write the trajectory equation for both cases.
