Two thin rod 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 0.76 kg attached to its free end. Rod B has a mass of 0.76 kg, which is distributed uniformly along its length. The length  of each rod is 0.72 m, and the angular speed is 4.4 rad/s. Find the kinetic energies of rod A with its attached particle and of rod B.
