Problem: A student knows that an ambulance siren has a frequency of fs = 393 Hz. He measures, when the ambulance is approaching him, the frequency fo = 415. Assume the speed of sound is 343 m/s in this problem.
Randomized Variables fs = 393 Hz
fo = 415 Hz
Part (a) Input an expression for the ambulance's speed, vs, in terms of the frequencies and the speed of sound v.
