A uniform solid disk made of wood is horizontal and rotates freely about a vertical axle at its center. The disk has radius 0. 600 m and mass 1. 60 kg and is initially at rest. A bullet with mass 0. 0200 kg is fired horizontally at the disk, strikes the rim of the disk at a point perpendicular to the radius of the disk, and becomes embedded in its rim, a distance of 0. 600 m from the axle.
