Answer :
The pilot should head his plane in the direction of vector of 76⁰.
The given parameters;
- velocity of the plane due south, a =160 mph
- velocity of the wind west, b = 40 mph
- Let the direction of the vector = θ
The direction of the vector can be determined by applying the principle of vector addition;
[tex]tan(\theta) = \frac{v_y}{v_x} \\\\\theta = tan^{-1} (\frac{160}{40} )\\\\\theta = 76 \ ^0[/tex]
Thus, the pilot should head his plane in the direction of vector of 76⁰.
