Math Help - Elastic and non-elastic collision

A bullet of mass m travelling at a velocity of v hits a block of mass M . After collision , the bullet is embedded in the block . The block is displaced through a height of h . Find the speed of the bullet in terms of m , M and h .

Sorry captain , there is a diagram for this question . I just cant find a way to post the diagram here .

The diagram shows a ballistic pendulum used to determine the speed of a bullet . A bullet of mass m travelling at a velocity of v hits a block of mass M . After collision , the bullet is embedded in the block . The block is displaced through a height of h . Find the speed of the bullet in terms of m , M and h .
