015 (part 1 of 2) 10.0 points An ambulance is traveling east at 58.5 m/s. Behind it a car travels along the same direc- tion at 30.2 m/s. The ambulance driver hears his siren with a wavelength of 0.45 L -30.2 m/s- -58.5 m/s- Ambulance Car What wavelength would a stationary ob- server behind the ambulance measure for the sound? The velocity of sound in air is 343 m/s. Answer in units of m. 016 (part 2 of 2) 10.0 points What wavelength would be measured on the
car's hood? Answer in units of m. 017 (part 1 of 2) 10.0 points An ambulance is traveling south at 59.4 m/s, away from a car that is traveling north at 32.5 m/s. The ambulance driver hears his siren at a frequency of 793 Hz. 59.4 m/s- -32.5 m/s →→ Ambulance Car What wavelength does a person who is standing between the car and the ambulance detect from the sound of the ambulance's siren? The velocity of sound in air is 343 m/s. Answer in units of m.
