A bat,flying at velocity V_B = 12.5 m//s ,isfollowed by a car running at velocity V_C = 50 m//s . Actual directions of the velocities of the car and the bat are as shown in the figure below, both being in the same horizontal plane (the plane of the figure). To detect the car, the bat radiates ultrasonic waves of frequency 36 kHz. Speed of sound at surrounding temperature is 350 m//s . There is an ultrasonic frequency detector fitted in the car. Calculate the frequency recorded by this detector. The ultrasonic waves radiated by the bat are reflected by the car. The bat detects these waves and from the detected frequency, it knows about the speed of the car. Calculate the frequency of the reflected waves as detected by the bat. (sin 37° = cos 53° ≈ 0.6, sin 53° = cos 37° ≈ 0.8)

Two trains A and B moving with speeds 20m//s and 30m//s respectively in the same direction on the same straight track, with B ahead of A . The engines are at the front ends. The engine of train A blows a long whistle. Assume that the sound of the whistle is composed of components varying in frequency from f_(1) = 800 Hz to f_(2) = 1120 Hz , as shown in the figure. The spread in the frequency (highest frequency - lowest frequency) is thus 320 Hz . The speed of sound in still air is 340 m//s .The speed of sound of the whistle is
