Since the pulley and the mass oscillate up and down by the same amount at the same frequency and you are told the combined mass, does this matter?

 

The trick with all these problems is to look for something  that is common to both parts.

This is homework so what have you done so far?

 

In particular can you at least describe in words what happens?
