A car is traveling down a straight, flat road at 22 m/s. A second car, behind the first, is traveling down the same road at 30 m/s. The driver of the second car is annoyed by the slow-moving car and sounds their horn which has a frequency of 250 Hz. Take the speed of sound in air to be 340 m/s. What frequency of sound does a child in the slow-moving car hear? a about 292 Hz about 256 Hz about 245 Hz about 215 HZ None of the above
