Step-by-step explanation:
= Time taken by the pebble to hit the water
= Time taken by the sound to travel to the observer
= Time taken by the observer to listen to the splash after stone is thrown = 3 s
a = g = Acceleration due to gravity =
= Speed of sound = 340 m/s
The distance traveled by the pebble
Distance traveled by the sound
The distance traveled by the sound and the pebble is equal
Since the value of
cannot be greater than 3.
So, time taken by the sound to reach the observer is 0.11 seconds.
Time taken by the pebble to hit the water is
Depth of the well is
