(Solved): Given v, find the norm/length of v, a unit vector, u, in the direction of v, and a unit vector, h, ...

Given $v$, find the norm/length of $v$, a unit vector, $u$, in the direction of $v$, and a unit vector, $h$, that is oppositely directed to $v$. Complete by hand, do not simplify, leave radicals as radicals, not decimals. $v=?\begin{array}{c}3\\ ?10\\ ?4\\ 2\end{array}?$; Norm of $v=$ Length of $v=$ $u=$ $h=$ $v=?\begin{array}{l}1\\ 0\\ 2\\ 1\\ 3\end{array}?$ Norm of Length of $v=$ $u=$ $h=$
