On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 20 m/s at an angle of 32° above the horizontal.
(a) How long was the ball in flight?
s
(b) How far did it travel?
m
(c) How much farther would it have traveled on the moon than on earth?
