A boat is traveling where there is a current of 0.20 m/s east. (Fig. 61). To avoid some offshore rocks, the boat must clear a buoy that is NNE (22.5^∘) and 3.0 km away. The boat's speed through still water is 21m/s. If the boat wants to pass the buoy 0.15 km on its right, at what angle should the boat head?
