The angular momentum is $=12063.7kgm^2s^-1$

The angular momentum is $L=Iomega$

The mass of the object is $m=5kg$

The radius of the path is $r=8m$

The moment of inertia of the object is given by

$I=mr^2$

$=5*8^2= 320 kgm^2$

The frequency is $f=6Hz$

The angular velocity is $omega=2pif=2*6*pi=12pirads^-1$

The angular momentum is

$L=Iomega=320*12pi=12063.7kgm^2s^-1$
