The magnitude of a velocity vector is called speed.
Chapter 12, Problem 12.82(choose chapter or problem)
The magnitude of a velocity vector is called speed. Suppose that a wind is blowing from the direction N W at a speed of 50 kmh. (This means that the direction from which the wind blows is west of the northerly direction.) A pilot is steering a plane in the direction N E at an airspeed (speed in still air) of 250 kmh. 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. 31. A
