how to calculate this??
An airplane P is heading N 80
o
W at 250 m/s relative to the air. The wind blows
from N 10
o
E with the speed of 40 m/s relative to the ground. Find the magnitude
and direction of the velocity of airplane P relative to the ground.
In the meantime, the velocity of airplane Q relative to the air is 250 m/s in the
direction of N 20
 Take g = 9.8 m/s
o
W. What is the speed of airplane Q relative to airplane P?
