5. You are hiking in a canyon and you notice an echo. You decide to let put a yell and notice it took 2 seconds before you heard the echo of your yell. How far away is the canyon wall that reflected your yell?
1 second each way
d = v *(1second)
where v = speed of sound
maybe around 340 meters/second
so I guess around 340 meters
so what was the problem?
To determine the distance to the canyon wall that reflected your yell, we need to consider the speed of sound and the time it took for the echo to reach you.
The speed of sound is approximately 343 meters per second (m/s) at room temperature. However, keep in mind that the speed of sound can vary depending on factors like temperature and humidity.
Since you heard the echo 2 seconds after yelling, it means that the sound traveled from you to the canyon wall and back to you. This round trip took 2 seconds.
We can divide the total time by 2 to find the time it took for the sound to reach the canyon wall:
2 seconds ÷ 2 = 1 second.
Now, we can calculate the distance by multiplying the time it took for the sound to reach the canyon wall by the speed of sound:
Distance = (Speed of sound) x (Time) = 343 m/s x 1 second = 343 meters.
Therefore, the canyon wall that reflected your yell is approximately 343 meters away.
To determine the distance to the canyon wall that reflected your yell, you can use the speed of sound. The speed of sound in air is approximately 343 meters per second at room temperature.
Since it took 2 seconds for you to hear the echo, we can assume that the sound traveled from you to the wall and back to you. So, the total distance traveled by the sound is twice the distance to the wall.
Using the formula: distance = speed × time, we can calculate the distance.
distance = 343 meters/second × 2 seconds
distance = 686 meters
Therefore, the canyon wall that reflected your yell is approximately 686 meters away from you.
