Question:

Obtain an expression for the angular deviation of a particle projected from the North Pole in a path that lies close to Earth. Is the deviation significant for a missile that makes a 4,800-lm flight in 10 minutes? What is the “miss distance” if the missile is aimed directly at the target? Is the miss distance greater for a 19,300-km flight at the same velocity?
