On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 7 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 23.9 m/s at an angle 29° above the horizontal. How much farther did the ball travel on the moon than it would have on earth? For how much more time was the ball in flight?

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 29 m/s at an angle 22 ∘ 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 July 17, 1969, while Apollo 11 was on its way to the Moon for the first Moon landing, The New York Times printed the following retraction of a 1920 editorial: On Jan. 13, 1920, “Topics of The Times,” an editorial-page feature of The New York Times, dismissed the notion that a rocket could function in a vacuum and commented on the ideas of Robert H. Goddard, the rocket pioneer, as follows: “That Professor Goddard, with his ‘chair’ in Clark...
