Apollo 14 astronaut Alan Shepard famously took two golfshots on the Moon where it’s been estimated that an expertlyhit shot could travel for 70.0 s through the Moon’s reducedgravity, airless environment to a maximum range of 4.00 km(about 2.5 miles). Assuming such an expert shot has a launchangle of 45.0°, determine the golf ball’s (a) kinetic energy asit leaves the club, and (b) maximum altitude in km above thelunar surface. Take the mass of a golf ball to be 0.045 0 kg andthe Moon’s gravitational acceleration to be gmoon = 1.63 m/s2.

Question

Apollo 14 astronaut Alan Shepard famously took two golf
shots on the Moon where it’s been estimated that an expertly
hit shot could travel for 70.0 s through the Moon’s reduced
gravity, airless environment to a maximum range of 4.00 km
(about 2.5 miles). Assuming such an expert shot has a launch
angle of 45.0°, determine the golf ball’s (a) kinetic energy as
it leaves the club, and (b) maximum altitude in km above the
lunar surface. Take the mass of a golf ball to be 0.045 0 kg and
the Moon’s gravitational acceleration to be gmoon = 1.63 m/s2.
