A sound wave traveling at 342 m/s is emitted
by the foghorn of a tugboat. An echo is heard
2.50 s later.
How far away is the reflecting object?
Answer in units of m.
the sound has to go there, and return.
2*distance=343m/s*2.50sec
To find the distance of the reflecting object, we can use the formula:
Distance = Speed × Time
In this case, the speed of sound is given as 342 m/s, and the time taken for the echo to be heard is 2.50 s.
Distance = 342 m/s × 2.50 s
Distance = 855 m
Therefore, the reflecting object is located 855 meters away from the source of the sound wave.
To determine the distance to the reflecting object, we can use the formula:
Distance = Speed x Time
1. First, we need to find the total time it took for the sound wave to travel from the foghorn to the reflecting object and back. Since the echo is heard 2.50 seconds later, we can divide this time by 2 to get the one-way time:
One-way time = 2.50 s / 2 = 1.25 s
2. Now that we have the one-way time, we can use the formula to find the distance:
Distance = Speed x Time
Distance = (342 m/s) x (1.25 s) = 427.5 m
Therefore, the reflecting object is approximately 427.5 meters away from the foghorn.
