In an experiment to determine the speed of sound, you drop a stone off down a deep well. Your miraculous vision allows you to see the stone hit the bottom of the well 6 seconds later. Half a second after that, you hear the impact of the stone. From this information, what is the speed of sound?

You stand at the top of a deep well. To determine the depth,
D, of the well you drop a rock from the top of the well
and listen for the splash as the rock hits the water’s surface. The
sound of the splash arrives t = 4.3 s after you drop the
rock. The speed of sound in the well is vs =
336 m/s

During a blackout, you are trapped in a tall building. You want to call rescuers on your cell phone, but you can't remember which floor you're on. You pry open the doors to the elevator shaft, drop your keys down the shaft, and hear them hit bottom at ground level 3.27 s later. Assume that the height of one floor is 3.0 m. 1.Making a simple calculation and remembering that the ground floor is numbered floor 1, you determine which...

9. The speed of sound was measured in a block of using a sound source and a detector, as shown, The source travels through the block and was detected at the opposite end. From this information, the time interval for the wave to travel the entire length of the block was measured and metal (mass density of 2.700x10 kg/m produced a sound wave that determined to be 8.14x10s seconds. i. Calculate the speed of the sound wave through the metal...
