Final answer:

The time taken by Superman to reach a scene after accelerating from 8.00 m/s to 7,930.23 m/s can be calculated using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken. By substituting the given values into the equation, we find that the time taken is approximately 4.13 seconds. Option E is correct.

Step-by-step explanation:

To calculate the time taken by Superman to reach a scene after accelerating from 8.00 m/s to 7,930.23 m/s with an acceleration of 187.1 m/s², we can use the equation:

v = u + at

Where:

v is the final velocity (7,930.23 m/s)

u is the initial velocity (8.00 m/s)

a is the acceleration (187.1 m/s²)

t is the time taken

Rearranging the equation and substituting the given values:

t = (v - u) / a

t = (7,930.23 m/s - 8.00 m/s) / 187.1 m/s²

t = 773.23 / 187.1 s

t = 4.13 s

Therefore, the time taken by Superman to reach the scene is approximately 4.13 seconds (option E).
