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 0.79 kg attached
to its free end. Rod B has a mass of 0.79 kg, which is distributed
uniformly along its length. The length of each rod is 0.73 m, and
the angular speed is 5.7 rad/s. Find the kinetic energies of rod A
with its attached particle and of rod B.
