This physics video tutorial explains how to solve the ballistic pendulum problem where a bullet is fired at a hanging wooden block. The bullet remains embedded in the block in an inelastic collision where kinetic energy is not conserved but momentum is conserved. The bullet block system rises to a height 'h' which this video explains how to calculate it using conservation of energy principles. Conservation of momentum occurs for any collision - elastic collisions and inelastic collisions. This video contains plenty of examples and practice problems.
