Consider a thin $40$ m rod pivoted at one end whose mass is $1$ kg $.$ A uniform density $1$ kg spherical object $($whose radius is $2$ m$)$ is attached to the end of the rod. The moment of inertia of the rod about an end is Irod $=13$ m L$2.$ The moment of inertia of the sphere about its center$-$of$-$mass is Isphere $=25$ m r$2.$ The acceleration of gravity g $=9\mathrm{.}8$ m$/$s $2.40$ m Cmass $1$ kg $1$ kg radius $2$ m $29$ Determine the moment of inertia of the rod plus mass system with respect to the pivot point. Answer in units of kg m$2.$
