A thin rod has a length of 0.684 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 0.937 rad/s and a moment of inertia of 1.09 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?
Find the magnitude of the acceration of each block. what is the magnitude of the average force exerted on the ball by the wall.

A laboratory ultracentrifuge is designed to produce a centripetal acceleration of 5.0 x 10^6 g at a distance of 4.00cm from the axis. What angular velocity in rev/min is necessary.
Two thin, isolated, concentric conducting spheres of radii 5.10 cm and 14.40 cm, have net charges of 23.00 nC, What is the electric potential at 3.315 cm from the center of the spheres
A barbell spins around a pivot at its center . The barbell consists of two small balls, each with mass m = 460 grams, at the ends of a very low mass rod whose length is L = 24 cm. The barbell spins with angular speed ω = 50 radians/s.
