Answer:
m/s
Step-by-step explanation:
Assumptions: 0° is true North, and 90° is east (along the x-axis).
To solve this problem we must use the expression:

Where
is the velocity in the y-direction (East),
is the total velocity in the direction which the aircraft is travelling, and
is the direction the aircraft is travelling (angle from the y-axis).
Using the equation above, we obtain the y-component of velocity
m/s which is rounded to 227 m/s (due to the number of significant figures in the question).
