# What is the angular momentum of a rod with a mass of #15 kg# and length of #6 m# that is spinning around its center at #24 Hz#?

##### 1 Answer

#### Explanation:

By definition, angular momentum is the cross product of the position vector from the axis of rotation to the rotating object and the linear momentum of the object.

That is,

So in this case, the magnitude of the angular momentum is

The direction of

So for example if the circular rotation is in the xy-plane formed by the basis unit vectors
