Due to a wind, the boat's actual speed relative to shore is 9/3 m/s in a direction 30° north of east. Find the speed and direction of the wind. Let c represent the current; this means that c| is the speed of the moving water and c points in the direction of the moving water. Assume that the vector w gives the speed and direction of the wind and the vector v, gives the speed and direction of the sailboat relative to the shore.

- Consider the following scenario. A pilot is steering a plane in the direction N 45° W at an air-speed (speed still in air) of 190 mi/h. A wind is blowing in the direction S 30° E at a speed of 34 mi/h. Set up the coordinate axes so that north is the positive y-direction and west is the negative x-direction. With respect to the still air, write a vector that represents the velocity of the plane and represents the velocity of the wind.
