A barbell of length d = 0.4 m is mountedon a massless rod of length b = 0.9 m. Thetwo small balls on the barbell are of massm = 0.4 kg. The apparatus is started in sucha way that the rod rotates clockwise with anangular speed !1 = 17 rad/s while the barbellrotates clockwise about its center with anangular speed !2 = 18 rad/s. Calculate the x component of the angu-lar momentum of the barbell due to rotationabout its own center, ~Lrot. Find the y component of the same vector.Answer in units of kg · m2/s Find the z component of the same vector.
