A body of mass $\displaystyle 5$ kg moving with a uniform speed $\displaystyle 3 \sqrt{2} m s^{-1}$ in $\displaystyle X-Y$ plane along the line $\displaystyle y=x+4$. The angular momentum of the particle about the origin will be $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{kg} \mathrm{m}^2 \mathrm{~s}^{-1}$.
