physics momentum question

A 34-g bullet travelling at 120 m/s embeds 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 N/m) a maximum of 1.2 cm. Calculate the mass of the block of wood.

Before doing the problem you must convert all units to SI. The spring stores potential energy, not kinetic!
