PhysicsQ&A LibraryA thin rod has a length of 0.106 m and rotates in a circle on a frictionless tabletop. The axis is perpendicular to the length of the rod at one of its ends. The rod has an angular velocity of 0.735 rad/s and a moment of inertia of 1.20 x 10-3 kg·m2. A bug standing on the axis decides to crawl out to the other end of the rod. When the bug (whose mass is 5 x 10-3 kg) gets where it's going, what is the change in the angular velocity of the rod?Question

A thin rod has a length of 0.106 m and rotates in a circle on a frictionless tabletop. The axis is perpendicular to the length of the rod at one of its ends. The rod has an angular velocity of 0.735 rad/s and a moment of inertia of 1.20 x 10^{-3} kg·m^{2}. A bug standing on the axis decides to crawl out to the other end of the rod. When the bug (whose mass is 5 x 10^{-3} kg) gets where it's going, what is the change in the angular velocity of the rod?
