15. Relation between sound and equations of motion

1. A stone is dropped from the top of a well, which is 5000 \(m\) high from the water surface.When is the splash heard at the top? (\(g\) = \(10\)\(m/s²\) and speed of sound(\(v\)) \(=\) 340 \(m/s²\))

 

 

Answer:

Thus, the total time taken by the splash sound to reach the top is  \(s\)
