Question

Tinku dropped the stone into a very deep well. He hears the sound 6.53 seconds after he dropped the stone. Find the depth of the well. Take acceleration due to gravity, g= 10m/s² and velocity of sound = 340 m/s.this question is a challenge for you!! please do it!!! Actually answer is 180m but I want the way how to solve it! if you know then solve!

Answer 1

Answer:

Explanation:

Time taken = time taken for stone to fall + time taken for sound to reach on top

$t = \sqrt{\frac{2h}{g} }  + \frac{h}{v}$

Solve the quadratic equation for h, t = 6.53, v = 340
