A ballistic pendulum is a device that was used to measure the speeds of bullets before the development of electronic timing devices. The devise consists of a large block of wood of mass 
, hanging from two long cords. A bullet of mass 
is fired into the block, the bullet comes quickly into rest and the block + bullet rises to a vertical distance 
before the pendulum comes momentarily to rest as the ends of the arc
In the process, the linear momentum is conserved. In such a collision, some kinetic energy is dissipated as heat; so mechanical energy is not conserved. When there is a loss in mechanical energy, the collision is said to be inelastic. Further when two bodies coalesce, the collision is said to be perfectly inelastic
