Question

A man is walking due south at 5km/h. The wind is blowing from the west at 8km/h. Find the magnitude and direction of the velocity of the wind relative to the man.

Answer 1

Let \( v_{wind} \) be the velocity of the wind; and \( v_{man} \) the velocity of the man. Then the velocity of the wind relative to the man is
\[ v_{wind} - v_{man} \]

Use this to draw a vector diagram and calculate the magnitude and direction of the vector.
