    Conservation of angular momentum on a frictionless table

    On a frictionless table, a glob of clay of mass 0.40 kg strikes a bar of mass 1.74 kg perpendicularly at a point 0.15 m from the center of the bar and sticks to it. If the bar is 1.14 m long and the clay is moving at 6.6 m/s before striking the bar, what is the final speed of the center of mass...
