Question

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 80.0cm .

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 80.0cm . 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 3.00rad/s as before. (Figure 2) What is the new angular momentum of the rod?

Explanation / Answer

The magnitude of angular momentum equals L = I x w, where w = angular frequency (the magnitude ofangular velocity) and I = moment of inertia for the long uniform rod rotating around the axis through center = 1/12 m x L
