The magnitude of velocity vector is called speed. Assume that a wind is blowing from direction N45°W at the speed of 60 km/h. (This means that the direction from which wind blows is 45° west of the northerly direction.) A pilot is steering plane in the direction N60°E at an airspeed (speed in still air) of 200 km/h. The true course, or track, of plane is the direction of the resultant of the velocity vectors of the plane and the wind. The ground speed of the plane is the magnitude of the resultant. Find the true course and the ground speed of the plane. Give your answers correct to one decimal place.
