Suppose you drop a rockinto a darkwell and, using precision equipment, you measure the time for the sound of a splash to return. (a) Calculate the time required for sound to travel up the well, calculate the distance tothe water if the sound returns in 2.0000s. (b) Now calculate the distance taking into account the time for sound to travel up the well. The speed of sound is 332.00m/s in this well.​
