A plane flying at 600 km / h to the north is held by a wind blowing 50 km / h from the north-east direction. What should the speed and direction of the plane be in order to go in the same direction (north)?
Solution approach:-
1. Draw a diagram with velocity of plane and velocity of air. (with
direction).
2. Take component of air velocity in East and South
directions.
3. Now assume velocity of air has two components (North and
East).
4. Balance East direction component of plane with the West
direction component of air.
5. Determine North direction component of plane using the fact that
velocity of plane in North should be 600. In other words, Velocity
of plane in North - Velocity of air in South = 600
6. By using point 4 and 5, both component of velocity of plane can
be calculated. Using both components, we can determine direction
and magnitude.
