the siren of a fire truck that is traveling northward at 40.0 m/s emits a sound wave of frequency 3000 Hz. a car in front of the truck is also traveling northward at 20.0 m/s. the temperature of the calm air outside (not windy) is 10.0 degrees Celcius. (a) what is the frequency of the siren's sound that the car driver hears? (b) what is the frequency of the siren's sound that the fire truck driver hears reflected from the car in front of it?
