Two thin rods of length L are rotating with the same angular speed ω (in rad/s) about axes that pass perpendicularly through one end. Rod A is massless but has a particle of mass 0.64 kg attached to its free end. Rod B has a mass of 0.64 kg, which is distributed uniformly along its length. The length of each rod is 0.89 m, and the angular speed is 4.9 rad/s. Find the kinetic energies of rod A with its...
