A barbell of length d = 0.4 m is mounted on a massless rod of length b = 0.9 m. The two small balls on the barbell are of mass m = 0.4 kg. The apparatus is started in such a way that the rod rotates clockwise with an angular speed !1 = 17 rad/s while the barbell rotates clockwise about its center with an angular speed !2 = 18 rad/s. Calculate the x component of the angular momentum of the barbell due to rotation about its own center. Find the y component of the same vector. Answer in units of kg · m2/s Find the z component of the same vector.
