Homework Help: physics

Posted by Jessi on Tuesday, March 24, 2009 at 12:36pm.

An 6.00 g bullet is fired into a 2.30 kg block initially at rest at the edge of a frictionless table of height 1.00 m. The bullet remains in the block, and after impact the block lands 2.00 m from the bottom of the table. Determine the initial speed of the bullet.

I know that the equation to solve for the initial velocity needs to be ((m_1+m_2)*v_f)/m_1 where m_1 is the mass of the bullet and m_2 is the mass of the block. What i don't know is how to get the final velocity in other terms so I can solve it.
