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 17 m/s at an angle of 30° above the horizontal. (a) How long was the ball in flight? (b) How far did it travel? (c) How much farther would it have traveled on the moon than on earth?
