A barbell consists of two small balls, each with mass 500 grams (0.5 kg), at the ends of a very low mass rod of length d = 25 cm (0.25 m). The center of the barbell is mounted on the end of a low mass rigid rod of length / = 0.375 m (see Figure), and this rod rotates clockwise with angular speed 100 rad/s. In addition, the barbell rotates clockwise about its own center, with an angular speed 80 rad/s B Part 1 (a) Calculate [ rot (both magnitude and direction). magnitude 1 kg . m2 /s direction Save for Later Attempts: 0 of 10 used Submit Answer Part 2 (b) Calculate L trans, 8 (both magnitude and direction). magnitude i kg . mz/'s direction
