A barbell consists of two small balls, each with mass 0.47kg, at the ends of a very low mass rod of length d =0.47m. The center of the barbell is mounted on the end of a low mass rigid rod of length b=0.55m, and this rod rotates clockwise wi addition, the barbell rotates clockwise about its own center, with angular speed 111rad/s. Calculate Lpa of the two balls about their center rotation (both magnitude and direction). 5.7622 kg m^2/s Incorrect No direction; zero magnitude. Correct: Into the page. Incorrect Out of the page.
