deep well at time t=0.
The sound of the stone
touching the water
surface of the well
reaches the dropping
point of the stone at
time t= 6.5 s. What is
the depth of the well
given, velocity of sound
in air = 360 m/s,
velocity of sound in
water is 1500 m/s,
acceleration due to
gravity is 10 m/s^2)
what is the time taken by the stone to touch the water surface? ​
