Alan Shepard hit 2 golf balls with a makeshift club on the moon during Apollo 14, jokingly for "miles." Shepard was barely able to hit the ball swinging one handed in a stiff pressurized suit trying to see through thick face glass. On Earth, good amateur golfers (two-handed, no pressure suit) can hit a ball say 90mph or 40m/s. Ignore air resistance and make the club hit so the ball is initially launched from about 45 degrees above the local horizontal. Given that the downwards acceleration due to the mass of the Earth at the Earth's surface is -9.81 m/s^2, what should the hang time of the ball typically be? Range for this hang?? 1. Sketch path and trig & explain calculations for Earth hang time and range. 2. Repeat your calculations (show your results in a table, don't explain) for: a. the Moon (g = -9.81 m/s^2 * 0.17), b. Mars (g = -9.81 m/s^2* 0.38), and c. planet Myworld where g = -9.81 m/s^2 *(0.45 + O.mm) where mm is the month of your birth.
