Consider a mechanical system (subject to gravity) consisting of an homogeneous bar, lying in the [tex]xy[/tex] -plane, of mass [tex]m[/tex], length [tex]\ell[/tex] and negligible section, with an extreme hinged in a fixed point [tex]P[/tex] of the [tex]y[/tex] axis. Now, suppose that the [tex]y[/tex]-axis is rotating with angular velocity [tex]\omega = \omega(t)[/tex]. What is the kinetic energy of the system?
