Question

What is the angular momentum of an object with a mass of `7 kg` that moves along a circular path of radius `12 m` at a frequency of `4 Hz`?

I

Answer 1

`"angular momentum="8064pi`

Explanation:

`"angular momentum=(moment of inertia) x (angular velocity)"`
`"moment of inertia :"I=m*r^2=7*12^2=7*144=1008`
`"angular velocity :"omega=2*pi*f=2*pi*4=8pi`
`"angular momentum=1"008*8pi`
`"angular momentum="8064pi`
