Consider the vector \(\vec{u} = (\sqrt{3},1)\). Find the vector \(\vec{w}\) such that \(\left |\vec{w}\right | = 4\) and the angle between \(\vec{u}\) and \(\vec{w}\) is \(60^{\circ }\). Find all solutions.
\(\vec{w} = (0,4)\), \(\vec{w} = (2\sqrt{3},-2)\)
\(\vec{w} = (0,-4)\), \(\vec{w} = (\sqrt{7},-3)\)
\(\vec{w} = (0,4)\), \(\vec{w} = (\sqrt{7},3)\)
\(\vec{w} = (\sqrt{5},\sqrt{11})\), \(\vec{w} = (2\sqrt{3},-2)\)
