The speed of sound in water is 1403 m/s. A sonar signal is sent from a ship at a point just below the water surface and 1.78 s later the reflected signal is detected. How deep is the ocean beneath the ship? Answer in units of m.

The ocean is 2497.34 meters beneath the ship.

Explanation:

Given that,

The speed of sound in water, v = 1403 m/s

A sonar signal is sent from a ship at a point just below the water surface and 1.78 s later the reflected signal is detected, t = 1.78 s

Let d is distance of the ocean beneath the ship. It is given by :

So, the ocean is 2497.34 meters beneath the ship.
