Answer:
The Resultant Vector
Explanation:
When two vectors are joined tail to tail and a parallelogram is completed in such a way that the resultant vector is always from common tail of the given vectors to the common head of two vectors.
So we have shown two vectors in this given diagram
red line is vector of velocity of airplane in forward direction which is of magnitude 150 km/h
while green line is another vector which is also another velocity
Now since these two vectors are connected tail to tail so the common diagonal here represented as resultant vector.
So correct answer is
Resultant Vector
