An airplane flies horizontally above the flat surface of a desert at an altitude of 5.00 km and a speed of 1000. km/h. If the airplane is to drop a bomb that is supposed to hit a target on the ground, where should the plane be with respect to the target when the bomb is released? If the target covers a circular area with a diameter of 50.0 m, what is the "window of opportunity" (or margin of error allowed) for the release time?
