Question

A stone is dripped into the well 44 meter dip the spalash in heard in 3.12 s find speed of sound in air.

Answer 1

The speed of sound is 366.67 m/s.

Step-by-step explanation:

height, h = 44 m

total time, T = 3.12 s

Let the time taken by the stone to hit the water is t.

use second equation of motion

`h = u t + 0.5 gt^2\\\\44 = 0.5* 9.8 t^2\\\\t = 3 s`

Time taken by sound to g up

t'=T - t = 3.12- 3 = 0.12 s

The speed of sound is

`v = (h)/(t')\\\\v = (44)/(0.12)\\\\v = 366.7 m/s`
