[Baton Twirling] A baton consists of with two identical masses m on the ends of a rod of length D and negligible mass. (a) What is the baton's angular momentum (magnitude and direction) about its center when twirling at constant angular speed ω about an axis through its center that is perpendicular to the rod (counterclockwise as seen from the top of this page)? (b) What is the baton's angular momentum (magnitude and direction) about its center when twirling at constant angular speed ω about an axis through its center that makes an angle θ with the rod (counterclockwise
