A bullet of inertia \(m_{\text {bullet }}\) is fired horizontally at a speed \(v_{\text {hullet, }}\) into a stationary wooden block of inertia \(m_{\text {block }}\) lying on a low-friction surface. The bullet passes through the block and emerges with a speed \(v_{\text {bullet,f. }}\). Determine the final speed of the block in terms of the given quantities.
