A glider aircraft initially traveling due west at 81.0 km/h encounters a sudden gust of wind at 37.0 km/h directed toward the northeast (see the figure below). What are the speed and direction of the glider relative to the ground during the wind gust? (The velocity of the glider with respect to the ground is the velocity of the gilder with respect to the wind plus the velocity of the wind with respect to the ground.) magnitude km/h direction ° north of west valid valider wind
