A ceiling fan has five blades, each with a mass of $0\mathrm{.}34$ kg and a length of $0\mathrm{.}66$ m$.$ The fan is operating in its $$low$$ setting at which the angular speed is $9\mathrm{.}4$ rad$/$s$.$ If the blades can be approximated as uniform thin rods that rotate about one end, what is the total rotational kinetic energy of the five blades?
