A plane traveled in the wind. The pilot needed to determine the flying angle to compensate for the effect of the wind. The pilot knew the wind vector (30 m/s, 220 degrees), and was paid to go to a destination at 140 degrees. The pilot wrote the destination vector as (unknown resultant speed, 140 degree) and the plane vector as (45 m/s, unknown flying angle). Use vector drawing to find the unknown resultant speed and unknown flying angle. Show a vector diagram with scale. Hints Draw the wind vector first, then use the end-tip of the wind vector to draw the destination vector as a line at 140 degrees, then use the start-tip of wind vector to draw a circle with radius 45 m/s. Use the intersection of the 45 m/s radius circle and the 140 degrees line to complete the vector triangle.
