A man A is sitting in a car at rest observes a man B on bike moving away from him with velocity 16 m/s^-1, a man C walking on road with velocity 2 m/s^-1 towards him and a bird flying with speed 20 m/s^-1 at angle 37 degree with horizontal as shown in (Fig. 5.74). Find the (a) velocity of car, bird, and man C as seen by man B. (b) velocity of car, bird, man B as seen by man C ( c) velocity of car, man B, and man C as seen by bird.
