At what distance from the ship is the iceberg if the ultrasonic signal sent by the sonar, having a speed of 1500 m / s, returned back after 5 seconds, if possible in detail.
The ultrasonic signal sent by the sonar reached the iceberg, reflected from it, and returned to the ship. Consequently, the signal has traveled a distance that is twice the distance from the iceberg to the ship. Therefore, we can find the distance we need by dividing by two the product of the signal speed and time: 2 * S = V * t = 1500 * 5 = 7,500 m => S = 7,500 / 2 = 3,750 m.
