Final answer:
The information provided does not directly answer the original question about aviation speed regulations; instead, it covers physics principles related to airspeed, power, and force encountered by aircraft. Without the correct regulatory details, we can only create an example physics problem addressing similar topics.
Step-by-step explanation:
The original question regarding airspeeds for aircraft operating at different flight levels (FL) seems to be related to aviation regulations, whereas the provided reference information is about physics problems involving concepts such as power, force, Bernoulli's principle, and the behavior of fluids and air in different situations. To appropriately answer the original question, one would need to know the regulations for aircraft airspeeds at the specified FL levels. Unfortunately, the reference information doesn't include such regulatory details. Therefore, I will be creating an example problem using the concepts from the reference information to illustrate how the physics of airspeed and flight can be applied to understand how an aircraft operates.
For instance, if we were to calculate the power required for an airplane to overcome air resistance at a certain altitude and airspeed, we can use the relation P = Fv, where P is power, F is force, and v is airspeed.
If an airplane with engines that produce 100 MW of power and mass 1.50×105 kg is supposed to reach an airspeed of 250 m/s and an altitude of 12.0 km, and if air resistance is negligible, we could ignore the force of air resistance in our calculations. However, if we were to include air resistance, as in case (c), we would need to determine the force of air resistance experienced by the aircraft during its ascent to 12.0 km altitude over a period of 1200 s. We would do this by considering the work done against air resistance and incorporating the distance traveled in 1200 s, assuming constant acceleration.
