A small 𝑚𝑏 = 09.0 ∗ 10−3 bug stands at one end of a thin uniform bar that is initially at rest on asmooth horizontal table. The other end of the bar pivots about a nail driven into the table and canrotate freely, without friction. The bar has a mass of 𝑀𝑏𝑎𝑟 = 49.0 ∗ 10−3𝑘𝑔 and is 𝐿𝑏𝑎𝑟 =100. 𝑐𝑚 in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with aspeed of 𝑣𝑏 = 21.0 𝑐𝑚𝑠 relative to the table. What is the angular speed of the bar just after the insectleaps? What is the total kinetic energy of the system just after the bug leaps? Where does thisenergy come from?

A majorette in a parade is performing some acrobatic twirlings of her baton. Assume that the baton is a uniform rod of mass 0.120 kgkg and length 80.0 cmcm .Figure1 of 2Part APart completeInitially, the baton is spinning about an axis through its center at angular velocity 3.00 rad/srad/s . (Figure 1)What is the magnitude of its angular momentum about a point where the axis of rotation intersects the center of the baton?Express your answer in kilogram meters squared per second.View Available Hint(s)for Part A1.92×10−2 kg⋅m2/skg⋅m2/sSubmitPrevious Answers CorrectPart BWith 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 3.00 rad/srad/s as before. (Figure 2) What is the new magnitude of the angular momentum of the rod about a point where the axis of rotation intersects the end of the baton?Express your answer in kilogram meters squared per second.View Available Hint(s)
