# 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 ?

Mar 5, 2016

$4019.2 k g {m}^{2} {s}^{-} 1$

#### Explanation:

Assuming the body as point mass the Angular momentum
L= $m {r}^{2} w = m {r}^{2} 2 \pi n$,
where m=mass =5kg
$L = 2 \cdot 5 \cdot {4}^{2} \cdot 3.14 \cdot 8 = 4019.2 k g {m}^{2} {s}^{-} 1$
