Velocity relative

An high altitude jet airplane has a velocity relative to the air of 320 m/sdue west. At a certain moment, the pilot notices a mountain peak directly west ofthe plane at a horizontal distance of 4.20 km. 10 s later, the peak is observed to bea horizontal distance 4.18 km away in a direction 17 degrees north of west.(a) Set up a coordinate system and given the components of the displacementvectors between the airplane and the mountain for both the initial and the final time.(b) Use the information above to find the wind velocity.
