asked 09/29/16Someone please help me, I cannot figure this problem out.
The cup on the 9th hole of a golf course is located dead center in the middle of a circular green which is 40 feet in radius. Your ball is located as in the picture below. The ball follows a straight line path and exits the green at the right-most edge. Assume the ball travels 8 ft/sec. Introduce coordinates so that the cup is the origin of an xy-coordinate system. Provide numerical answers below with two decimal places of accuracy.
(a) The x-coordinate of the position where the ball enters the green will be .
(b) The ball will exit the green exactly seconds after it is hit.
(c) Suppose that L is a line tangent to the boundary of the golf green and parallel to the path of the ball. Let Q be the point where the line is tangent to the circle. Notice that there are two possible positions for Q. Find the possible x-coordinates of Q:
smallest x-coordinate =
largest x-coordinate =

The golf green is a circle with radius 40 feet and its center at the origin, so its equation is:
x² + y² = 1600
However, the diagram showing the ball's starting position and path is missing from the question.
Please upload the picture so I can calculate the exact numerical answers for parts (a), (b), and (c), including all the work and answers rounded to two decimal places.
