A pilot wishes to fly to a point 450 km due south in 3 hours. A windis blowing from the west at 50 km/hr. By means of a vector diagram, compute the proper heading and speed that the pilot must choose to achieve this objective.
The vector sum of the velocity with respect to air (speed and heading) and the wind velocity vector must be 150 km/s in a south direction.
Write that as a vector equation and solve for the unknown components.
