Question

Recompose the displacement vector, d, with the following X and Y components. Dy= 9.04m down and Dx=6.68m left

Answer 1

Down and to the left will be in the third quadrant

tan θ = 9.04 / 6.68 = 1.35 and θ = 53.5 deg below the negative x-axis

So D = (180 + 53.5) (Dx^2 + Dy^2)^1/2

D = 11.2 tan 233.5

Or D = -6.68 i - 9.04 j
