Answer:
clockwise from the south.
Explanation:
Given:
- velocity of the plane southwards,
- velocity of the wind in south-west,
- ∴Angle between the plane and wind velocities,
<u>According to the vector addition rule, magnitude of the resultant velocity is given as:</u>
is the plane's speed with respect to ground.
Direction of this resultant with respect to south:
clockwise from the south.
