a ship is 850 m from a vertical cllff the ship sireN IS SOUNDED AN ECHO IS HEARD AFTER 5 SECOND CALCULATE THE SPEED OF THE SOUND FROM THE SIREN OF THE SHIP
d = V*t = 800 m.
V * 5/2 = 800
V = 320 m/s.

To calculate the speed of sound, we'll use the formula:
speed = distance / time.
In this case, the distance is the total distance the sound travels (from the siren to the cliff and back), and the time is the time it takes for the echo to be heard.
First, let's calculate the total distance traveled by the sound. Since the ship is 850 meters away from the cliff, and the sound travels from the ship to the cliff and then back to the ship, the total distance is twice the distance from the ship to the cliff:
Total distance = 2 * 850 meters = 1700 meters.
Next, we'll use the time provided, which is 5 seconds, to calculate the speed of sound:
Speed of sound = Total distance / time.
= 1700 meters / 5 seconds.
Now, let's do the calculation:
Speed of sound = 1700 meters / 5 seconds.
= 340 meters per second.
Therefore, the speed of sound from the siren of the ship is 340 meters per second.
