A displacement vector in a coordinate plane has components

A_x = 3.0 \times 10^{2}\,\text{m}

and

A_y = -4.0 \times 10^{2}\,\text{m}

. (i) Calculate the magnitude of the displacement. (ii) Determine the angle the vector makes with the positive

x

–axis, specifying the correct quadrant. (iii) Express the vector in terms of its magnitude multiplied by a unit vector along its own direction.
