QUESTION 3 Time left 1:49:33 An AES speed detection radar emits a beam of microwaves at a frequency designated as fe. The beam reflects by an approaching car, and the radar picks up and analyzes the reflected beam's frequency, fr. Because of the car's motion, the reflected beam's frequency is shifted slightly from fe to fr. The relationship between the speed of the car, v, in kilometres per hour and the two microwave frequencies, is: V = (6.685 x 108) * ( fr - fe fr + fe X 1.60934 Where the emitted waves have a frequency of fe=2x1010 s-1. AES application will request the value of the reflected beam's frequency, fr. The program then calculates the car's speed before sending a warning message if the speed exceeds the set limits. The defined speed limit is 120 km/h. If the car's speed is larger than or equal to this, the program will display a warning message, "Vehicle is over the speed limits!" otherwise, the program will not display any warning. (a) Sketch a flowchart for the above problem-solving.
