ASK YOUR TEACHER As shown below, the red train is stationary and the green train is moving forward at a speed of 25 m/s. Between the trains is a bicyclist moving forward at 14.5 m/s. Each train has a whistle with a frequency of 142 Hz. The air temperature is 38°C. A.) What is the frequency from the red train's whistle as heard by the bicyclist? B.) What is the frequency from the green train's whistle as heard by the bicyclist? MY NOTES
