Question

Example 3.72 An aeroplane has to go from a point O to another point A, at distance d due 37° East of North. A wind is blowing due North at a speed of 10 ms. The air speed of the plane is v. (i) Find the direction in which the pilot should head the plane to reach the point A. (ii) Find the time taken by the plane to go from 0 to A​

Answer 1

Explanation:

The vector diagram for various velocities is shown.Vector AC gives velocity of aeroplane relative to quiet air.Vector CB gives velocity of wind(air) relative to ground.Vector AB gives velocity of plane relative to ground.
