find the depth of the well in the following mechanics question... a very deep well is drilled vertically through the earth. when a brick is dropped into the shaft the sound of the brick hitting the bottom is heard 11.4 seconds later. taking the speed of sound to be 350 ms, find the depth of the well.
We know that:
Speed = Distance/ Time
Given the speed = 350 m/s
Also, given the time = 11.4 seconds.
Then we will calculate the distance.
==> 350 = Distance / 11.4
==> Distance = 350 * 11.4 = 3990 m
Then, the depth of the well is 3990 meters.
