A ballistic pendulum to be uaed to measure the speed of a bullet is constructed by suspending a block od woos of Mass M by a cord of length L

The pendulum initially hangs vertically at rest.  A bullet of mass m is fired into the block and becomes embedded in it.  

The penulum then begins to swing and rises until the cord makes a maximum angle 'a' with the vertical

Find the initial speed of the bullet in terms of M, m, L, and a by applying the appropriate conservation laws
