Suppose you drop a rock at rest into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. neglecting the time required for sound to travel up the well, calculate the distance to the water if the sound returns in 2.4700 s. then calculate the distance taking into account the time for sound to travel up the well. the speed of sound in this case is 340.00 m/s as well.
