B$)$ As shown in the figure, $4\mathrm{.}00-$kg and $3\mathrm{.}00-$kg mass are attached to opposite ends of a thin $40\mathrm{.}0-$cm$-$long horizontal rod. The system is rotating at an angular speed of $6\mathrm{.}0ra\frac{d}{sec}$ about a vertical axle at the center of the rod. Determine $($a$)$ the kinetic energy K of the system and $($b$)$ the net force on each mass. $($c$)$ Repeat parts $($a$)$ and $($b$),$ assuming that the axle passes through the CM of the system

Determine:

$($a$)$ The kinetic energy $K$ of the system,
