A boat is travelling in a flowing river. Fig. 1.1 shows the velocity vectors for the boat and the river water.

The velocity of the boat in still water is 14.0 m s−114.0\ \text{m s}^{-1} to the east. The velocity of the water is 8.0 m s−18.0\ \text{m s}^{-1} from 60∘60^{\circ} north of east.

(i)

On Fig. 1.1, draw an arrow to show the direction of the resultant velocity of the boat.
