A uniform rod of mass M = 2.3 kg and length L = 0.2 m, lying on a frictionless horizontal plane, is free to pivot about a vertical axis through one end, as shown. The moment of inertia of the rod about this axis is given by 1/3 ML2. If a force F = 7 N, q = 47° acts as shown, what is the resulting angular acceleration (in rad/s2) about the pivot point?

A cylinder with rotational inertia 0.050 kg m2 is spinning with angular velocity 25 rad/s, clockwise with negligible friction about a vertical axis.

A uniform, 0.0300 kg rod of length 0.400 m rotates in ahorizontal plane about a fixed axis through its center and perpendicularto the rod. Two small rings, each with mass 0.0200 kg, are mounted sothat they can slide without friction along the rod. They are initially heldby catches at positions 0.0500 m on each side of the center of the rod,and the system is rotating at 48.0 rev/min. With no other changes in thesystem, the catches are released, and the rings slide outward along therod and fly off at the ends. What is the angular speed (a) of the systemat the instant when the rings reach the ends of the rod; (b) of the rodafter the rings leave it?
