Two thin rods of length L are rotating with the same angular speed ? (in rad/s) about axes that pass perpendicularly through one end. Rod A is massless but has a particle of mass 0.66 kg attached to its free end. Rod B has a mass of 0.66 kg, which is distributed uniformly along its length. The length of each rod is 0.75 m, and the angular speed is 4.2 rad/s. Find the kinetic energies of rod A with its attached particle and of rod B.

Two thin rods of length $L$ are rotating with the same angular speed $\omega$ (in $\mathrm{rad} / \mathrm{s}$ ) about axes that pass perpendicularly through one end. Rod $\mathrm{A}$ is massless but has a particle of mass $0.66 \mathrm{kg}$ attached to its free end. Rod B has a mass of 0.66 kg, which is distributed uniformly along its length. The length of each rod is $0.75 \mathrm{m},$ and the angular speed is $4.2 \mathrm{rad} / \mathrm{s}$. Find the kinetic energies of rod $A$ with its attached particle and of rod $B$.
