Moment of inertia of a rod about its center of mass:

$\boxed{\mathit{i}\mathbf{=}\frac{\mathbf{1}}{\mathbf{12}}\mathit{m}{\mathit{l}}^{\mathbf{2}}}$

Where m is mass and l is length

Angular momentum:

$\boxed{\mathbf{L}\mathbf{=}\mathit{i}\mathbf{\omega }}$

m = 560 g(1kg/1000g) = 0.56 kg

Length, l = 2.0m
