An airplane flies horizontally from east to west at 318 mi divided by hr relative to the air. if it flies in a steady 34 mi divided by hr wind that blows horizontally toward the southwest (45degrees south of west), find the speed and direction of the airplane relative to the ground. assume that the vector w gives the direction and speed of the wind, the vector bold v subscript p gives the direction and speed of the airplane relative the air, and the vector v gives the direction and speed of the airplane relative to the ground. place the vectors in a coordinate system. choose the correct diagram below.
