What is the angular momentum of an object with a mass of 5 kg that moves along a circular path of radius 3 m at a frequency of  16 Hz ?

The angular momentum is $= 4523.9 k g m {s}^{- 1}$

Explanation:

The angular momentum is

$L = I \omega$

where $I$ is the moment of inertia

and $\omega$ is the angular velocity

For the object, $I = \left(m {r}^{2}\right)$

So, $I = 5 \cdot {\left(3\right)}^{2} = 45 k g {m}^{2}$

$\omega = 16 \cdot 2 \pi r a {\mathrm{ds}}^{-} 1$

$L = 45 \cdot 32 \pi = 4523.9 k g m {s}^{- 1}$
