A bullet of mass mb is fired horizontally with speed v1 at a wooden block of mass mw resting on a frictionless table. The bullet hits the block and becomes completely embedded within it. After the bullet has come to rest within the block, the block, with the bullet in it, is traveling at speed . What is the speed of the block/bullet system after the collision? Express your answer in terms of v1,mb mw, and
