A barbell consists of two small balls, each with mass 500 grams (0.50 kg), at the ends of a very low mass rod of length d = 45 cm (0.45 m). The center of the barbell is mounted on the end of a low mass rigid rod of length b = 0.675 m (see Figure), and this rod rotates clockwise with angular speed 120 rad/s. In addition, the barbell rotates clockwise about its own center, with an angular speed 120 rad/s.
Calculate L_trans (both magnitude and direction).
Calculate L_tot (both magnitude and direction.
