Question

What is the angular momentum of an object with a mass of `7 kg` that moves along a circular path of radius `2 m` at a frequency of `19 Hz`?

Answer 1

`L=532*pi`

Explanation:

`m=7 kg`
`r=2m`
`f=19Hz`
`L=I* omega "(angular momentum")`
`I=m*r^2 ("r:radius,m:mass")`
`L=m*r^2* omega`
`omega =2*pi*f "(omega :angular velocity)"`
`L=7*2*2 pi*19`
`L=532*pi`
