Pilot wants to fly an airplane due north, but there's a 65km/hwind blowing towrd teh east. (a) In what direction should the pilot head the plane if its speed relative to the air is 340km/h?(b) draw a vector diagram to illustrate it. (c) If the pilot decreases the air speed of the plane, but still wants to head duenorth, should the angle found in part (a) be increased ordecreased?
