Question

What is the angular momentum of an object with a mass of `2 kg` that moves along a circular path of radius `4 m` at a frequency of `12 Hz`?

Answer 1

`P=768pi" "kg*m^2*s^-1`

Explanation:

`P=I*omega`
`I=m*r^2 " Moment of inertia"`
`omega=2*pi*f`
`P=m*r^2*2*pi*f`
`P=2*4^2*2*pi*12`
`P=4*16*12*pi" "P=64*12*pi`
`P=768pi" "kg*m^2*s^-1`
