A majorette in a parade is performing some acrobatic twirlings of her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm . A. Initially, the baton is spinning about an axis through its center at angular velocity 3.00 rad/s . (Figure 1) What is the magnitude of its angular momentum about a point where the axis of rotation intersects the center of the baton? B.With a skillful move, the majorette changes the rotation of her baton so that now it is spinning about an axis passing through its end at the same angular velocity 3.00 rad/s as before. (Figure 2) What is the new amplitude of the angular momentum of the rod about a point where the axis of rotation intersects the end of the baton?
