The USGA (United States Golf Association) regulate the coefficient of restitution (COR) in golf clubs, with the current limit being 0.83. Any club with a COR higher than 0.83 is ruled non-conforming and illegal according to PGA standards. The new LIV Golf Tour, which is funded out of Saudi Arabia, decides to ignore this rule and allows its golfers to use whatever driver they want. Greg Norman, one of the supporters and golfers on this LIV Tour decides to use a 0.90 COR golf club instead of the regulated 0.83 COR golf club. Determine how much further the golf ball would travel horizontally in meters before hitting the ground using a 0.90 COR golf club compared to a 0.83 COR golf club if the speed of both golf clubs was 95 miles per hour when making contact with the 45-gram ball. The angle that the golf ball is traveling when it leaves the surface of the golf club in both scenarios is 20 degrees above the horizon and the mass of the golf club head is 200 grams. In answering this question, determine the following: a) Resultant velocity of the ball leaving the club head in both scenarios (0.83 & 0.90 COR) (2 pt) b) Initial horizontal and vertical velocities of the golf ball immediately after leaving the club head and taking flight for both scenarios (4 pt) c) The time that the golf ball spent in the air for both scenarios (2 pt) d) Horizontal displacement by the golf ball in both scenarios before bouncing on ground (2 pt) e) How much further the golf ball travelled horizontally before hitting the ground when using the 0.90 COR golf club compared to the 0.83 COR golf club.
