a) Using property given,

$I={I}_{cm}+M{d}^{2}$

Here,$d=\frac{L}{2}$

Hence,

$I=\frac{M{L}^{2}}{12}+\frac{M{L}^{2}}{4}=\frac{M{L}^{2}}{3}$

b) Using shift property of moment of inertia

$I=\frac{M{\alpha}^{2}}{6}+\frac{M{\alpha}^{2}}{2}=\frac{2M{\alpha}^{2}}{3}$

Here,

Hence,

b) Using shift property of moment of inertia

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?

The popularity of fads and fashions often decays exponentially. One example is ticket sales for a popular movie. The table shows the total money spent per weekend on tickets in the United States and Canada for the movie The Da Vinci Code.

a) Use a graphing calculator to create a scatter plot of the data.

b) Draw a quadratic curve of best fit. - Press STAT, cursor over to display the CALC menu, and select 5:QuadReg. - Press VARS, and cursor over to display the Y-VARS menu. Select 1:Function and then select 1:Y1. - Press ENTER to get the QuadReg screen, and press GRAPH.

c) Draw an exponential curve of best fit. - Press STAT, cursor over to display the CALC menu, and select 0:ExpReg. - Press VARS, and cursor over to display the Y-VARS menu. Select 1:Function and then select 2:Y2. - Press ENTER to get the ExpReg screen, and press GRAPH.

d) Examine the two curves. Which curve of best fit best models the data?
