(9%) Problem 7: Apollo 14 astronaut Alan B. Shepard Jr. used an improvised six-iron to strike two golf balls while on the Fra Mauro region of the moon's surface, making what some consider the longest golf drive in history. Assume one of the golf balls was struck with initial velocity vo = 31.5 m/'s at an angle 0 = 210 above the horizontal. The gravitational acceleration on the moon's surface is approximately 1/6 that on the earth's surface. Use a Cartesian coordinate system with the origin at the ball's initial position.
