What is the speed of the bullet in this conservation of m problem?

A 2.0 kg wood block hangs from the bottom of a 1.0 kg, 1.0-m long rod. The block and rod form a pendulum that swings on a frictionless pivot at the top end of the rod. A 10 g bullet is fired into the block, where it sticks, causing the pendulum to swing out to a 30 degree angle. What was the speed of the bullet. NOTE: the rod has a specific m and length and must be factored into the calculation
