A speaker on a car produces a 150 Hz sound wave when parked. The car starts to drive toward a pedestrian standing by the road, and the pedestrian hears the sound shift to 160 Hz when the car starts to drive toward them. The car passes the pedestrian and drives away from them. What frequency would the pedestrian hear as the car drives away? Assume the speaker continuously produces the same frequency, the car maintains the same speed, and the...

Sam plays on her violin the concert A with frequency 440 Hz. Brian is at a distance of 5.0 m from Sam, playing on a flute at the same frequency. Sam remains stationary, while Brian is in motion. (a) If Brian moves according to x (t) = 5+0.45 t2, how much time passes before Sam hears a beat frequency of 15 beats/s? Do not forget to include the time it takes for sound to travel to Sam. (b) If Brian...
