Question

A stone is dropped into a well a sound is produced and heard after 2.5 second. Find the depth of the well if the velovity of sound is 330 m per second

Answer 1

time to hear = time taken for stone to go down + time taken for sound to come up

time taken for stone to go down = t1=
$\sqrt{ \frac{2h}{g} }$
time taken for stone to come up = h/330= t2

according to question
t1+t2 = 2.5
now solve for H in t1 .. make this brainliest
