An airplane approaches at an altitude of 10 km flying at 600 km/hr. a. Jet engines typically emit sound over a wide spectrum of frequencies, with the maximum sound energy at 200 Hz. From this emitted sound, what frequency do you hear initially when it is 1 minute away, and what frequency do you hear 1 minute after it has passed by? b. What would you hear, and when would you hear it, if the plane were "hypersonic", traveling three times the speed of sound, or "Mach 3"? That's approximately the fastest military aircraft in routine service today. To have higher speeds in air takes considerably more energy. For example, after two and half minutes of flight, when the first-stage main engines of the Space X Falcon shut down, it is 80 kilometers high and moving at Mach 10 on its way to Earth orbit. The Mach number depends on the temperature of the air.
