# What is the angular momentum of a rod with a mass of # 8 kg# and length of #4 m# that is spinning around its center at #12 Hz#?

##### 1 Answer

The answer is

#### Explanation:

Angular momentum is similar in formula to linear momentum:

To find the moment of interia

In the case of a rod being rotated about its centre, the moment of inertia is

The angular velocity

Put it together:

which is approximately 804
