The Space Shuttle travels at a speed of about 5.45 x 103 m/s. The blink of an astronaut's eye lasts about 111 ms. How many football fields (length = 91.4 m) does the Space Shuttle cover in the blink of an eye?
vt/L=5.45•10³•111•10⁻³/91.4 =6.62
To find out how many football fields the Space Shuttle covers in the blink of an eye, we need to determine the distance traveled by the Space Shuttle in that amount of time.
We know the speed of the Space Shuttle is 5.45 x 10^3 m/s, and the blink of an eye lasts about 111 ms (milliseconds).
First, let's convert the blink of an eye time from milliseconds to seconds:
111 ms = 111 x 10^-3 s = 0.111 s
Now, we can calculate the distance traveled by the Space Shuttle in this time:
Distance = Speed x Time
Distance = 5.45 x 10^3 m/s x 0.111 s
Distance = 605.95 m
Next, we need to convert this distance to football fields. Given that the length of a football field is 91.4 m:
Number of football fields = Distance / Length of a football field
Number of football fields = 605.95 m / 91.4 m
Number of football fields ≈ 6.63
Therefore, the Space Shuttle covers approximately 6.63 football fields in the blink of an eye.
