The water in a river moves south at 10 km/hr. A motorboat is traveling due east at a speed of 38 km/hr relative to the water, determine the speed of the boat relative to the shore. Let w represent the current; this means that | w| is the speed of the moving water and w points in the direction of the moving water. Assume that the vector Vw gives the direction and speed of the boat relative the water, and the vector V. gives the direction and speed of the boat relative to the shore. Place the vectors in a coordinate system. Choose the correct diagram below. O A. O B. N O c. N OD. W -z w W - N W - W Vw Vw W W VW
