a thin rod has a length of 0.25m 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 0.27 rad/s and a momentum of intertia of 9.00 x 10^-4 kg.m^2. A bug standing on the axis decided to crawl out to the other end of the rod. When the bug (mass = 4.2 x 10^-3 kg) gets where it's going, what is the angular velocity?
