Find the total kinetic energy of a dumbbell of total mass m when it is rotating at an angular speed of w, and its center of mass is moving translationally with a speed of v. Denote the dumbell's moment of inertia about its center of mass as Icm. If you approximate the spheres as point mass of m/2 each located at a distance of r from the center, you can find an approximation for the center of mass (though it is not required for this problem).

A uniform rod of mass 200 g and length 100 cm is free to rotate in a horizontal plane around a fixed vertical axis through its center, perpendicular to its length. Two small beads, each of mass 20 g, are mounted in grooves along the rod. Initially, the two beads are held by catches on opposite sides of the rod’s center, 10 cm from the axis of rotation. With the beads in this position, the rod is rotating with an angular velocity of 10.0 rad/s. When the catches are released, the beads slide outward along the rod. (a) What is the rod’s angular velocity when the beads reach the ends of the rod? (b) What is the rod’s angular velocity if the beads fly off the rod?
