Sound travels at 343 m/s in the air. What distance from the student is the lightning strike, in meters? Write an expression that describes the skydiver's average speed, v1 during the period before opening the chute in terms of the given quantities.
Expression.
v1 = ______________________
To determine the distance from the student to the lightning strike, we can use the speed of sound in air.
The speed of sound is given as 343 m/s, which means that sound travels 343 meters in one second. However, since we are looking for the distance from the student to the lightning strike, we need to consider only the time it takes for the sound to reach the student.
The sound of thunder is caused by the lightning, and since light travels much faster than sound, we see the flash of lightning almost instantaneously while the sound takes some time to reach us. By measuring the time difference between seeing the lightning and hearing the thunder, we can determine how far away the lightning strike was from us.
To calculate the distance, we need the time it took for sound to reach the student. Let's say the time difference between seeing the lightning and hearing the thunder is t seconds.
The distance traveled by sound can be calculated using the formula:
Distance = Speed × Time
Therefore, the distance from the student to the lightning strike is:
Distance = 343 meters/second × t seconds
Now, let's represent this expression in terms of the given quantities.
Expression:
Distance = 343t
This expression represents the distance from the student to the lightning strike in terms of the given quantities.
