I'm having some difficulties with this problem, even though it seems easy.(adsbygoogle = window.adsbygoogle || []).push({});

-----A bullet with a mass of 3.20 g is fired horizontally at two blocks resting on a smooth and frictionless table top as shown in the Figure. The bullet passes through the first 1.05 kg block, and embeds itself in a second 1.00 kg block. Speeds v1 = 4.60 m/s and v2 = 4.60 m/s, are thereby imparted on the blocks. The mass removed from the first block by the bullet can be neglected. Find the speed of the bullet immediately after emerging from the first block. Find the intial speed of the bullet.------

The second part I assume will be easier to figure out once I get the first part. For the first part I thought I could use the equation m1vi1 + m2vi2 = m1vf1 + m2vf2....but I keep trying to do it and I get lost and get wrong answers. Could anyone be so kind as to point me in the right direction? Thanks )
