A stone is dropped from the top of the tower 500m high into a pond of water at the base of the tower. When is the splash heard at the top? Given, g = 10 m/s sq. and speed of sound = 340 m/s.

The total distance the stone travels= 500m. After stone hitting the water surface sound has to travel 500 m to reach the top of the tower. So total time is taken = time taken by stone to travel down(t1)+time taken by sound to travel up (t2)
