A uniform solid sphere of radius

r $=0\mathrm{.}440$ m

and mass

m $=17\mathrm{.}0$ kg

turns counterclockwise about a vertical axis through its center $($when viewed from above$),$ at an angular speed of $2\mathrm{.}80$ rad$/$s$.$ What is its vector angular momentum about this axis? $($Enter the magnitude in kg $$ m$2/$s$.)$
