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 70.50 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°, determine the golf ball's kinetic energy as it leaves the club, and maximum altitude in km above the lunar surface. Take the mass of a golf ball to be 0.0450 kg and the moon's gravitational acceleration to be g(moon) = 1.63 m/s2. (a)kinetic energy as it leaves the club (in J)
(b)maximum altitude in km above the lunar surface
