Question

An airplane is traveling in the direction 20 degrees west of north at 700 ​km/hr. Find the component form of the velocity of the​ airplane, assuming that the positive​ x-axis represents due east and the positive​ y-axis represents due north.

Answer 1

(-239.4, 657.8) km/h

Explanation:

Measured CCW from the +x axis, the angle at which the airplane is traveling is 110°. Then the (x, y) components of the velocity vector are ...

(700 km/h)(cos(110°), sin(110°)) ≈ (-239.4, 657.8) km/h
