a stone is dropped into a well 44 meter deep and the sound of speash is heared after 3.12 second find the speed of sound air

Answer 1

Time to reach bottom = t s
distance
44 m= (1/2)gt^2
where
g=acceleration due to gravity = 9.8 m/s²
=>
t=sqrt(2*44/g)=2.997 s
Subtract this time from 3.12 seconds will be the time needed for sound to travel 44 m.
Use
Distance=speed × time
to find speed of sound.
