Question: On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The acceleration due to gravity on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 23 m/s at an angle 25 degrees above the horizontal.
(a) How much farther did the ball travel on the moon than it would have on earth?
(b) For how much more time was the ball in flight?
