a. Alan Shepard famously hit golf balls on the moon using a six iron. As he was limited to a one-handed swing due to his spacesuit and gloves it is unlikely it was at optimum velocity. However, one of the highest recorded speeds for a golf ball is 226 mph, or about .1 km/sec. Using that velocity, is it possible for a golf ball to achieve escape velocity from the lunar surface by using only a golf club? (show by calculation). b. The Apollo 11 lunar module orbited the moon at an average altitude of about 190 km. What is the lunar escape velocity at that altitude? c. What orbital delta V would be required to achieve the escape velocity calculated in (b)?

3. Escape velocities:
a. Alan Shepard famously hit golf balls on the moon using a six iron. As he was limited to
a one-handed swing due to his spacesuit and gloves it is unlikely it was at optimum
velocity. However, one of the highest recorded speeds for a golf ball is 226 mph, or
about .1 km/sec. Using that velocity, is it possible for a golf ball to achieve escape
velocity from the lunar surface by using only a golf club? (show by calculation).
b. The Apollo 11 lunar module orbited the moon at an average altitude of about 190 km.
What is the lunar escape velocity at that altitude?
c. What orbital delta V would be required to achieve the escape velocity calculated in
(b)?
