Suppose the observer remains at x = 0 and a source emits a frequency fs. If the source travels from x = −100 to x = 100 (passing “through” the observer) over the interval of time 0 ≤ t ≤ 10. 1. How fast is the source traveling? 2. What is x(t) that gives the position of the source? 3. If fs = 440 hz, what is fo at each time t? (Write as a piecewise function.) 4. Does your answer match your intuition/experience?

If a sound with frequency fs is produced by a source traveling along a line with speed vs. If an observer is traveling with speed vo along the same line from the opposite direction toward the source, then the frequency of the sound heard by the observer is fo = c + vo c − vs fs where c is the speed of sound, about 332 m/s. (This is the Doppler effect.) Suppose that, at a particular moment, you are...
