Answer:
Step-by-step explanation:
In part 3.b.i, we calculated the time it took for the sound to travel from the source to the observer:
t = 0.0466 seconds
We can use this time and the speed of sound in air to calculate the distance traveled by the sound wave:
d = v * t
where v is the speed of sound in air and t is the time.
d = 340 m/s * 0.0466 s
d = 15.844 m
This is the round-trip distance traveled by the sound wave, which includes the distance from the source to the building and back. To find the one-way distance from the observer to the building, we need to divide this distance by 2:
d/2 = 15.844 m / 2
d/2 = 7.922 m
Therefore, the length of the school field, which is the distance between the observer and the building, is approximately 7.922 meters.
