Question
A plane wants to fly east. It is capable of flying at 250 m/s, yet a 50 m/s wind is blowing [SW]. What heading must the plane set and what will be the plane's speed relative to the ground?
Answers
the plane must fly northeasterly so that its north velocity component equals the south velocity component of the wind
250 sin(Θ) = 50 sin(45º)
250 sin(Θ) = 50 sin(45º)
