OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
