(a) Is the sound traveling toward the left or right when it reaches the car? (b) What is the frequency heard on the car? (c) When the car passes the train, is the sound traveling to the left or right when it reaches the car? (d) Then what frequency is heard on the car? 30 m/s Train Car 120 m/s 30 m/s Train Car 120 m/s 22K. A highway is parallel to a railroad track and a car is approaching a train as shown.
