an abulance with its siren sounding is moving in a horizontal direction at constant velocity. it has a 380Hz horn in it. use 343m/s for speed of sound for air if needed. (A) when the ambulance is moving toward you, you meansure a frequency of 390Hz. determine the speed if the ambulance givwn that you remain stationary. (B) After the ambulance passes and starts moving away from you, you start to move in yhe opposite direction of the ambulance. what is your velocity when you measure a frequency of 375Hzv
