Homework Help: Physics- so confused!!

Posted by Julia on Saturday, March 23, 2013 at 10:09pm.

A bullet with a mass of 5.40 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 1.20 kg block, and embeds itself in a second 1.20 kg block. Speeds v1 = 3.90 m/s and v2 = 1.70 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 initial speed of the bullet.
