Two thin rods of length l are rotating with the similar, Ask an Expert

Academics

Two thin rods of length L are rotating with the similar angular speed ω (in rad/s) about axes that pass perpendicularly through one end. Rod A is mass less 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 regularly along its length. The length of each rod is 0.77 m, and the angular speed is 5.7 rad/s. Discover the kinetic energies of rod A with its attached particle and of rod B.
