An high altitude jet airplane has a velocity relative to the air of 320 m/s

due west. At a certain moment, the pilot notices a mountain peak directly west of

the plane at a horizontal distance of 4.20 km. 10 s later, the peak is observed to be

a 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 displacement

vectors between the airplane and the mountain for both the initial and the final time.

(b) Use the information above to find the wind velocity.
