Answer to Problem 80AYU
Explanation of Solution
Given:
Air speed of the planeis
Bearing
Speed of wind is
Bearing
Calculation:
As the Air speed of the plane is
Therefore,
Velocity of plane is
And the wind speed of the plane is
Velocity of wind is
Therefore, resultant vector is equal to the actual velocity of plane.
And the ground speed is
Now, to find its direction:
Therefore, bearing is
Hence, the direction and magnitude of the resultant vector is
