Aplane flying from townsville, australia, has an air speed of 264 m/s in a direction 5.0° south of west. it is in the jet stream, which is blowing at 37 m/s in a direction 15° south of east. in this problem you are going to be asked about the velocity of the airplane relative to the earth.

Speed of plane is 300.5 m/s at angle of 6.22 degree South of West

Explanation:

Air speed of the plane is given as

v = 264 m/s in direction 5 degree South of West

So we have

Also we have speed of air is given as

v = 37 m/s at 15 degree South of West

so it is

So the net speed of plane with respect to ground is given as

so it is

direction is given as
