A police officer is at rest on the side of a road, when a car speeds past her. She aims a radar gun at the car, emitting an electromagnetic wave at a frequency of f0 = 24.15 GHz. The wave is absorbed by the car and re-emitted, returning to the radar gun with a frequency that is 5.4 Hz lower than the original frequency f0.
Find the speed of the car.?
