The Space Shuttle travels at a speed of about 7.60 103 m/s. The blink of an astronaut's eye lasts about 120 ms. How many football fields (length = 91.4 m) does the Shuttle cover in the blink of an eye?

9.1

To find out how many football fields the Space Shuttle covers in the blink of an eye, we need to calculate the distance traveled by the Shuttle in that time.

Given:
Speed of the Space Shuttle = 7.60 × 10^3 m/s
Blink duration = 120 ms

First, we need to convert the blink duration from milliseconds to seconds:
120 ms = 120 × 10^-3 s = 0.12 s

Next, we can calculate the distance traveled by the Shuttle in that time:
Distance = Speed × Time
Distance = 7.60 × 10^3 m/s × 0.12 s
Distance = 912 m

Now, we can calculate the number of football fields (length = 91.4 m) covered in this distance:
Number of football fields = Distance ÷ Length of a football field
Number of football fields = 912 m ÷ 91.4 m
Number of football fields ≈ 9.99 football fields

Therefore, the Space Shuttle covers approximately 9.99 football fields in the blink of an eye.

To find out how many football fields the Space Shuttle covers in the blink of an eye, we can calculate the distance traveled by the Shuttle in 120 milliseconds and then convert it to football fields.

First, let's calculate the distance traveled by the Space Shuttle in the blink of an eye:

Distance = Speed × Time

Given:
Speed of the Space Shuttle = 7.60 × 10^3 m/s
Time (blink of an eye) = 120 ms = 120 × 10^-3 s

Substituting the values into the formula:
Distance = (7.60 × 10^3 m/s) × (120 × 10^-3 s)

Now let's perform the calculation:

Distance = (7.60 × 10^3) × (120 × 10^-3) m

To simplify, we can multiply the numerical values:
Distance = 9.12 × 10^2 m

Now that we know the distance traveled in meters, we can convert it 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

Substituting the values into the formula:
Number of football fields = (9.12 × 10^2 m) / (91.4 m)

Now let's perform the calculation:

Number of football fields = (9.12 × 10^2) / 91.4

To simplify, we can divide the numerical values:
Number of football fields = 10

Therefore, the Space Shuttle covers approximately 10 football fields in the blink of an eye.

d = 7.6*10^3 * 0.12s = 912m.

912m / 91.4m/field = 9.98 Football field.
