Component Form of Velocity of an Airplane
Given Data:
Direction of an airplane is 30° west of north at 800km/hr.
To Find: Component form of velocity
Solution:
Lets draw the picture.
The angle between the velocity vector and the negative X-axis is 60° (= 90°-30°). Using the definitions of the trigonometry functions
Then we have the:
X-component of velocity = -800cos(60°)
Y-component of velocity= 800sin(60°)
This is the component form of the velocity of the airplane.
