Question
(a) A jet airplane flying from Darwin, Australia, has an air speed of 260 m/s in a direction $5.0^\circ$ south of west. It is in the jet stream, which is blowing at 35.0 m/s in a direction $15^\circ$ south of east. What is the velocity of the airplane relative to the Earth? (b) Discuss whether your answers are consistent with your expectations for the effect of the wind on the plane's path.
