III 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 hit the ball with a speed of 25 m/s at an angle 30° above the horizontal.
- How long was the ball in flight?
- How far did it travel?
- Ignoring air resistance, how much farther would it travel on the moon than on earth?
