Astronaut Alan Shepard famously hit a golf ball from the Moon's surface, where the acceleration of gravity is only 1.62m/s2. Assuming the ball launched at a speed of 25.0 m/s (his swing was slow due to the bulky space suit) and an angle of 40.0o above the horizon, how far away did the ball land? Assume a constant gravitational acceleration of 1.62m/s2, no air resistance (the Moon has no atmosphere), and that the surface of the Moon is flat over these distances.
You sing into a well and find that the well resonates at frequencies of 231 Hz and 273 Hz with no resonances between these two frequencies. What is the frequency of the fundamental mode
