Two masses $m_1$ and $m_2$ are attached to a rod of negligible mass that is capable of rotating about an axis perpendicular to the rod and passing through the end, A $,$ as shown in the diagram below. The length of the rod is $l=19\mathrm{.}0cm,m_1=2\mathrm{.}00g,m_2=4\mathrm{.}50g,x_1=2\mathrm{.}70cm,$ and $x_2=7\mathrm{.}30cm.$ If the rod rotates counterclockwise in the $x-z$ plane with an angular speed of $5\mathrm{.}00ra\frac{d}{s},$ what is the angular momentum of the system? We use the standard rectangular coordinate system with $+x$ axis to the right, $+y$ axis vertically up$,$ and $+z$ axis coming out toward you. Enter your answer using unit vector notation.

vec$(L{)}_{\text{t}\text{o}\text{t}\text{a}\text{l}}=$

Treat the two masses as point particles. What is the moment of inertia of a mass $m$ located a distance $r$ from the axis of rotation? Review the definition of angular momentum of an object moving with a speed $v.$ kg $-\frac{m^2}{s}$
