What is the new angular momentum of the rod

Reference no: EM13548982

A majorette in a parade is performing some acrobatic twirlings of her baton. Assume that the baton is a uniform rod of mass 0.120kg and length 80.0m 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. What is the new angular momentum of the rod?
