minus-squareteftlink53•edit-214 days agoMy napkin math says around 1000 meters. If the rock falls for 14-15 seconds and takes 3 seconds to echo up the chamber that’s about 1000 meters either way terminal velocity and speed of sound.
minus-square@Carvexlink23•14 days agoNerdier math puts the 14 second total time as 12s falling and 2s sound returning, for a depth of 700m. Your napkin was fairly close!
minus-square@[email protected]linkfedilink15•edit-214 days agoThank you! Edit: the other acceptable answer is “deep af.” But I appreciate that you took it seriously and shared.
