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.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
