The cup on the 9th hole of a golf course is located dead center in the middle of a circular green that is 70 feet in diameter. Your ball is located as in the picture below: green 50 feet ball 40 feet X / cup rough The ball follows a straight line path and exits the green at the right-most edge. Assume the ball travels a constant rate of 10 ft/sec. (Let the coordinates of the cup be (x, y) = (0, 0).) (a) Where does the ball enter the green? (Round your answer to four decimal places.) (x, y) = ball path (b) When does the ball enter the green? (Round your answer to two decimal places.) 3.19 sec X (c) How long does the ball spend inside the green? (Round your answer to two decimal places.) 5.82 sec (d) Where is the ball located when it is closest to the cup? (Round your answer to four decimal places.) (x, y) = When is the ball closest to the cup? (Round your answer to two decimal places.) 6.10 sec
