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?
If eight people greet each other at a meeting by shaking hands with one another, how many handshakes take place?
Obtain the differential equation of the family of curves described.
1. Straight lines with slope equal to twice of the x-intercept
2. Circles with fixed radius r and tangent to y-axis
3. Parabolas with vertex and focus on the y-axis
