An airplane travels at speed of 125 m/s in calm air. The plane wants to undergo a change of displacement delta x= 183 km i. The wind velocity is -26 m/s i + 38 m/s j.
a. Draw a triangle representing the velocity of the plane with respect to the ground , the plane with respect to the air, and the air with respect to the ground.
b. What are the east- west and north- south components of the plane's velocity with respect to the air?
c. At what angle should the plane orient itself?
d. How lond will it take the plane to reach its destination?
