A point is currently at position

$,$

$,$

and is rotating about the origin with angular velocity

$.$ The speed of the particle is

and

is parallel to the vector

$.$

Matlab$/$Octave

Mathematica

Python

R

SymPy

from sympy import $*$

x $=4$

y $=-5$

z $=-4$

vMag $=4$

u $=$ Matrix$([3,-5,2])$

What is the magnitude

of the angular velocity vector?
