Question

What is the angular momentum of a rod with a mass of `8 kg` and length of `6 m` that is spinning around its center at `1 6 Hz`?

Answer 1

`"Angular Momentum"=3072pi`

Explanation:

`"Angular Momentum"=I*omega`
`I:"moment of inertia"`
`omega:"angular velocity"`
`omega=2*pi*f" "omega=2*pi*16" "omega=32pi`
`I=1/3ml^2`
`"Moment of inertia for a rod spinning around its center"`
`I=1/3*8*6^2" "I=12*8=96`
`"Angular Momentum"=32*96pi`
`"Angular Momentum"=3072pi`
