Question

Several vectors in the x-y plane are shown in the figure with their tails at the origin of the coordinate system and with a label at their heads. Two of these vectors are given in terms of the unit-vectors i and j as P = (2.20i + 5.30j) and Q = (-5.30i + 5.40j), where the numbers are measured in meters.

Identify vectors P and Q in the figure.
