Suppose that a wind is blowing in the direction S45E at a speed of 40 km/h. A pilot is steering a plane in the direction N60E at an airspeed (speed in still air) of 100 km/h. The true course, or track, of the 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. (Round your answers to one decimal place.) true course N 53.3 ground speed 97.6 XE X km/h
