A spring fixed to a wall is attached to a 6 kg block of wood on the other end. The block rests on a frictionless surface. The spring with spring constant 100 N/m is compressed by 0.1 m and releases. With what frequency and period will the block/spring system oscillate?

Question

A spring fixed to a wall is attached to a 6 kg block of wood on the other end. The block rests on a frictionless surface. The spring with spring constant 100 N/m is compressed by 0.1 m and releases. With what frequency and period will the block/spring system oscillate? 
-I drew the diagram, and the givens: K=100 N/m, F=0.1 m, and you're trying to find the frequency (f) and Period (T). But the equations to find both of those are reciprocal… f=1/T T=1/f, so I don't know how to find them.. Please help!
