The vector written in its components is given by: u = lul * (cos (theta) i + sin (theta) j) Substituting values we have: u = 4 * (cos (30) i + sin (30) j) Rewriting we have: u = 4 * ((root (3) / 2) i + (1/2) j) u = 4 * (root (3) / 2) i + 4 * (1/2) j u = 2 * root (3) i + 2j u = 3.5i + 2j Answer: The component form of this vector is: u <3.5,2>
