Thanks! I'm guessing that what you hinted at was that in case one- bullet hits block, momentum is conserved. I rearranged this and solved for the velocity of the block/bullet pair in terms of the bullet's mass, the blocks unknown mass and the initial bullet velocity. Then, I used law of...

Homework Statement A 34.0 g bullet traveling at 122 m/s emdeds itself in a wooden block on a smooth surface. The block then slides toward a spring and collides with it. The block compresses the spring, k=99.0 N/m, a maximum of 1.20 cm. Calculate the mass of the block of wood. Homework...
