Answer : The SI unit for angular momentum is \quad kg.m^2.s^{-1} and its dimension is M.L^2.T^{-1}.

Explanation : Angular Momentum is the rotational motion equivalent of the Linear Momentum of Translational motion. It is defined as the moment of Linear Momentum.

\vec{L} \equiv \vec{r}\times\vec{p}= \vec{r}\timesm\vec{v}

L = r.mv.\sin\theta; \qquad \sin\theta is a unitless quantity.
SI units for m, r and v are, respectively, kg, m and m.s^{-1}.
