QUESTION 1 A horn sounds a 307 Hz tone. How fast would you have to run away from it for it to sound like 235 Hz? (v = 343 m/s)

Step 1
Rearranging the formula, we get: u = (f' - f) (v + us) / f Substituting the values, we get: u = (235 Hz - 307 Hz) (343 m/s + u) / 307 Hz Simplifying the equation, we get: u = -0.22 u + 75.5 m/s Solving for u, we get: u = 96.8 m/s Show more…

A sound source plays middle $\mathrm{C}(262 \mathrm{Hz})$. How fast would the source have to go to raise the pitch to $\mathrm{C}$ sharp $(271 \mathrm{Hz}) ?$ Use $343 \mathrm{m} / \mathrm{s}$ as the speed of sound.

Properties and Detection of Sound
A person in a parked car sounds the horn. The frequency of the horn's sound is $489 \mathrm{~Hz}$. A driver in an approaching car measures the frequency of the horn's sound as $509.4 \mathrm{~Hz}$. What is the speed of the approaching car? (Use $343 \mathrm{~m} / \mathrm{s}$ for the speed of sound.)
A sound source plays middle C (262 Hz). How fast would the source have to go to raise the pitch to C sharp (271 Hz)? You may assume the receiver is stationary.
