Question

What is the angular momentum of an object with a mass of `5 kg` that moves along a circular path of radius `4 m` at a frequency of `8 Hz`?

Answer 1

`4019.2kgm^2s^-1`

Explanation:

Assuming the body as point mass the Angular momentum
L= `mr^2w=mr^2 2pin`,
where m=mass =5kg
radius of circular path.r=4m
frequeny of rotation n = 8Hz
`L=2*5*4^2*3.14*8=4019.2kgm^2s^-1`
