a stone is thrown into a well and the splash is heard after 3s. (speed of sound : 340m/s) . 1.) What time did the stone take to reach the water? 2.) how long did it take for the sound to reach the observer? 3.) What is the depth of the well ?
P.s this question was super difficult for me even my physics teacher couldnt do it ( I know it's a shame) but I'm giving 50 points , so geeks start solving.
