On a strange planet where the acceleration due to gravity is 6.7 m/s2 , a rock is thrown downward at 3.00 m/s into a dark well and the time until the sound of a splash is heard is measured. Using 250.0 m/s for the velocity of sound on this planet, determine the actual distance to the surface of the liquid at the bottom of the well (not water!). If the sound is heard 5.000 seconds later.

An astronaut on a distant planet wants to measure the acceleration due to gravity there by timing pulses (waves) travelling along a wire fixed at each end and with a mass hanging from it (i.e. hanging mass is causing a tension in the wire). She has measured the length and mass of the wire to be 1.60 metres and 3.55 grams. The mass hanging from the wire is 2.9 kgs. If the pulse takes 35.7 milliseconds to travel the full...
