Baton question part b
Initially, the baton is spinning about a line through its center at angular velocity 3.00 rad/s.
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 velocity3.00 rad/s as before. (Part B figure) What is the new angular momentum of the rod?
(Original momentum was 1.92*10^-2 kg*m^2/s)
