A classically evil antagonist decides to push their child out the door of a car and drive away at a speed of 15.0 m/s (54.0 km/h). While driving away, the antagonist hears the child scream a constant wailing note at 301 Hz while the child remains at rest in the parking lot beside a stationary kitten. Assuming the speed of sound is 343 m/s, the frequency of the note as heard by the kitten is Hz. Note: Object is moving towards to the observer
