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?

A group of investigators measured calcium intake in three different treatment groups. The data are provided in Table 1. The researchers used a one-way ANOVA test to compare the difference between three treatment groups. Using alpha=0.05, what would be their conclusion?

Fail to reject the null hypothesis and conclude that the three group have the same mean of Calcium measurement. Stop there.

Fail to reject the null hypothesis and conclude that the three groups do not have the same mean of Calcium measurement. Stop there.

Reject the null hypothesis and conclude that the three groups do not have the same mean of Calcium measurement. Move on with multiple comparisons.

At t=0 the current to a dc electric motor is reversed, resulting in an angular displacement of the motor shaft given by 𝜃(𝑡) = (250 𝑟𝑎𝑑/𝑠 )𝑡 − (20.0 𝑟𝑎𝑑/𝑠 2 )𝑡 2 − (1.50 𝑟𝑎𝑑/𝑠 3 ) 𝑡 3 . (a) At what time is the angular velocity of the motor shaft zero? (b) Calculate the angular acceleration at the instant that the motor shaft has zero angular velocity. (c) How many revolutions does the motor shaft turn through between the time when the current is reversed and the instant when the angular velocity is zero? (d) How fast was the motor shaft rotating at t=0 when the current was reversed? (e) Calculate the average angular velocity for the time period from t=0 to the time calculated in part (a). A
