Full question: The magnitude or length of a velocity vector is called the speed. Suppose that a wind is blowing from the direction N45◦W at a speed of 50 km/h (this means the direction from which the wind is blowing is 45◦ west of the northerly direction). A pilot is steering a plane in the direction N60◦E at an airspeed (the speed in still air) of 250 km/h. The true course or track of the plane is the direction of the sum of velocity vectors of the plane and of the wind. The ground speed is the length or magnitude of this sum of velocity vectors. Find the true course, expressed as a traditional compass bearing (like N45◦W, N60◦E), and the ground speed of the plane #Angles #techniques #VectorHelp
