A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm.

With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

Does there exist a non-commutative algebraic structure with the following properties?

1. $|M|\ge 2$

2. For all $a$, $b$, $c$ $\in M$, $(a\cdot b)\cdot c=a\cdot (b\cdot c)$.

3. For all $a$, $b$ $\in M$ with a≠b, exactly one of the equations $a\cdot x=b$ and $b\cdot x=a$ has a solution for $x$ in $M$.

4. For all $a$, $b$ $\in M$, the equation $a\cdot x=b$ has a solution for $x$ in $M$ if and only if the equation $y\cdot a=b$ has a solution for $y$ in $M$.
