An ambulance siren sounds off with a frequency of 250Hz as it approaches an intersection where you are standing as a spectator. You hear the siren with a frequency of 175Hz. a) Assuming the speed of sound is 340m/s, what is the speed of the ambulance? b) After the ambulance passes, you begin to walk at a pace of 2m/s in the opposite direction as the ambulance. Assuming the speed of the ambulance stays the same. What is the new frequency you hear the siren at?
