A man fires a rifle in front of a cliff and hears the echo after 3s. Calculate the distance of man from the cliff, if velocity of sound in air is 340 m/s.
Question
A man fires a rifle in front of a cliff and hears the echo after 3s.
Calculate the distance of the man from the cliff, if the velocity of sound in air is 340 m/s.
Solution
To calculate the distance of the man from the cliff, we can use the formula:
Distance = (Velocity of Sound × Time) / 2
Given that the velocity of sound in air is 340 m/s and the time it takes for the echo to reach the man is 3 seconds, we can substitute these values into the formula:
Distance = (340 m/s × 3 s) / 2
Simplifying the equation, we get:
Distance = 510 m / 2
Distance = 255 m
Therefore, the man is approximately 255 meters away from the cliff.
