A woman drops a rock into a well. The woman hears the sound of the splash 1.50 seconds after releasing the rock. The speed of sound in the w is 336 m/s. a. Show a velocity-time graph for the rock as it falls from the surface down the well, and the sound of the splash as the sound comes up the well. b. How far below the top of the well is the surface of the water?

A person leaning over a 122 m -deep well accidentally drops a siren emitting sound of frequency 2450 Hz . Just before this siren hits the bottom of the well, find the frequency and wavelength of the sound the person hears Just before this siren hits the bottom of the well, find the frequency of the sound the person hears coming directly from the siren. Just before this siren hits the bottom of the well, find the wavelength of the...

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

A boy stands at a dark well and wants to investigate how deep this well is. He therefore throws a stone into the well and after 2.6 seconds he hears the sound of the stone hitting the water surface. If the sound velocity is assumed infinitely high and it is assumed that one can ignore the air resistance of the stone. Sound speed at sea level is approximately 340 m / s. Approximately how large a deviation from the above...

An airplane reaches its takeoff speed of 60 m/s with constant acceleration in 30 s, starting from rest. The time it takes to go from 40 m/s to 60 m / s is: A car starts moving from rest with an acceleration of 0.40 m/ s2. A minute later the acceleration stops, and the car moves with constant speed for 5.0 minutes. The car's brakes are finally applied and stops in 2.0 minutes slowing evenly. The total distance traveled by...

A phsyics student standing on the top floor of a building wishes to determine the depth of the elevator shaft. They drop a rock from rest and hear it hit the bottom after 2.81s. a) How far (in m) is it from where the drop the rock to the bottom of the shaft. The speed of sound at the temperature of ai in the shaft is 336 m/s. Use g=9.80m/s^2 b) If the travel time for the sound is ignored,...
