What is the direction of angular velocity in circular motion about a fixed axis of rotation?

The direction of the angular velocity vector is along

What is the value of linear velocity if $\overrightarrow{r} = 3\widehat{i} + 4\widehat{j} + 6\widehat{k}$ and $\overrightarrow{\omega} = -5\widehat{i} + 3\widehat{j} + 5\widehat{k}$?

The left end of a massless stick with length $l$ is placed on the corner of a table,as shown in the figure. $A$ point mass $m$ is attached to the center of the stick,which is initially held horizontal. It is then released. Immediately afterward,what normal force does the table exert on the stick?

Write the formula expressing the relationship between linear velocity and angular velocity for a particle in rotational motion.

What is the direction of angular velocity for a rigid body?
