Problem
An observer walks due north at 2.0ms−1 past a factory whistle that is mounted 12m west of the sidewalk and is stationary with respect to the ground. At the instant the observer is directly east of the whistle (closest approach), is the frequency that the observer hears greater than, less than, or equal to the whistle’s 520Hz rest frequency? Justify your answer in one or two sentences.
