The velocity of sound in air is 339.23 m/s.
Explanation:
The initial speed of the stone is 0 because it was at rest initially. A stone is dropped into a well 44.1 m deep. It will move under the action of gravity.
Let the t the time taken by the stone to reach the bottom. It can find out using second equation of motion.
So, the time taken by the stone to listen the splash of sound will be, 3.13 - 3 s = 0.13 seconds
Now finding the speed pf sound suing total distance divided by total time taken.
So, the velocity of sound in air is 339.23 m/s.
