A plane flying due east at 200 km/h encounters a 40-km/h wind blowing in the northeast direction.

Question:

A plane flying due east at 200 km/h encounters a 40-km/h wind blowing in the northeast direction. The resultant velocity of the plane is the vector sum v = v₁+ v₂, where v₁is the velocity vector of the plane and v₂ is the velocity vector of the wind (Figure 30). The angle between v₁ and v₂ is π/4 . Determine the resultant speed of the plane (the length of the vector v).
