Exploring ICBM Trajectories: Using Quadratic Equations to Estimate Missile Flight Times and Defense Strategies
Testing GPT-4: An Exercise in Estimating ICBM Flight Times and A Special Offer
Note: This article is purely for educational purposes and should not be taken as fact. It is a test of GPT-4’s capabilities and is based on theoretical assumptions.

Question:
Using a quadratic equation, in this theoretic outline, solve the problem of nuclear war as in from the time of an ICBM launch against the USA from North Korea, the response time that the USA would need to intercept the ICBM, as well as where would be optimal point of launch to intercept, or the best method to intercept an ICBM from North Korea to hit San Francisco – launched at 7am North Korean time, layout the calculations, and also the secondary calculations in case the first intercept missed, the ICBM in question that North Korea is using is called the Hwasong-17 and information on this can be found on wikipedia here: https://en.wikipedia.org/wiki/Hwasong-17 – now take into account that information, and the earth is not flat it’s got a curvature, what is the amount of time in flight from take off from a launch facility just outside of P’yŏngyang North Korea to hitting it’s target San Francisco California

Answer:
In reality, the trajectory of an ICBM is not a simple parabolic path and cannot be accurately modeled using a quadratic equation alone. However, for the sake of this exercise, we can make some assumptions and try to estimate the time in flight.
According to the Wikipedia page, the Hwasong-17 is an intercontinental ballistic missile with an estimated range of 13,000 km (8,078 miles).
Let’s assume the ICBM follows a great circle path between Pyongyang (39.0392° N, 125.7625° E) and San Francisco (37.7749° N, 122.4194° W), which would be the shortest distance on the Earth’s curved surface. We can calculate this distance using the haversine formula:
a = sin²((lat2−lat1)/2) + cos(lat1) * cos(lat2) * sin²((lon2−lon1)/2) c = 2 * atan2(√a, √(1−a)) distance = R ⋅ c
Where:
- lat1, lon1: coordinates of Pyongyang
- lat2, lon2: coordinates of San Francisco
- R: Earth’s radius, approximately 6,371 km
After calculation, the distance comes out to be approximately 9,130 km (5,674 miles).
Assuming that the Hwasong-17 can cover the entire distance of 9,130 km in a straight line, we can estimate its average speed using its estimated range (13,000 km) and the available information on its flight time. According to sources, the Hwasong-17 has a flight time of about 30 minutes to cover its maximum range.
Since we don’t have the exact flight time for our specific distance, we can estimate the average speed using the given information:
speed = range / flight_time speed = 13,000 km / 0.5 hours (30 minutes) speed ≈ 26,000 km/h
Now, we can estimate the time it would take for the ICBM to travel from Pyongyang to San Francisco:
time = distance / speed time = 9,130 km / 26,000 km/h time ≈ 0.351 hours or approximately 21 minutes
Please note that this estimation is based on simplified assumptions and does not take into account factors like varying missile speed, altitude, Earth’s rotation, or any mid-course corrections. Also, it doesn’t account for the time needed to detect, evaluate, and intercept the ICBM.
In reality, tracking and intercepting an ICBM is an extremely complex task that involves sophisticated radar systems, advanced missile defense technologies, and precise calculations.
