Q. An airplane pilot sets a compass course due west and maintains an airspeed of 213 . After flying for a time of 0.510 , she finds herself over a town a distance 121 west and a distance 12 south of her starting point. Find the magnitude of the wind velocity. Find the direction of the wind velocity.If the wind velocity is 39 due south, in what direction should the pilot set her course to travel due west? Use the same airspeed of 213 .
