What is the value of linear velocity, if $\vec \omega = 3\hat i - 4\hat j + \hat k$ and $\vec r = 5\hat i - 6\hat j + 6\hat k$
What is the value of linear velocity, if $\vec \omega = 3\hat i - 4\hat j + \hat k$ and $\vec r = 5\hat i - 6\hat j + 6\hat k$
$6\hat i - 2\hat j + 3\hat k$
$6\hat i - 2\hat j + 8\hat k$
$4\hat i - 13\hat j + 6\hat k$
$ - 18\hat i - 13\hat j + 2\hat k$
What is the value of linear velocity, if $\vec \omega = 3\hat i - 4\hat j + \hat k$ and $\vec r = 5\hat i - 6\hat j + 6\hat k$
$\vec v = \vec \omega \times \vec r $
$=\left|{\,\begin{array}{*{20}{c}}{\hat i}&{\hat j}&{\hat k}\\3&{ - 4}&1\\5&{ - 6}&6\end{array}\,} \right|$
$ = - 18\hat i - 13\hat j + 2\hat k$
