3.42. Set Up: The relative velocities are the raindrop relative to the earth, the raindrop relative to the train, and the train relative to the earth, is due east and has magnitude is west of vertical. is vertical. The relative velocity addition diagram is given in Figure 3.42. Figure 3.42 Solve: (a) is vertical and has zero horizontal component. The horizontal component of is so is westward. (b) 3.43. Set Up: Solve: We want to be due south. The relative velocity addition diagram is shown in Fig- ure 3.43. Figure 3.43 (a) west of south. (b) Reflect: The speed of the bird relative to the ground is less than its speed relative to the air. Part of its velocity rela- tive to the air is directed to oppose the effect of the wind. 3.44.
