I've attached the problem as a .jpg file. The mass obviously has potential energy. Is this simply converted to the kinetic energy of the mass plus the two kinetic energies of the pulleys? I also don't see how I would find the angular speed (probably don't even need to) of the pulleys. Cant simply due the gravity acceleration over the distance on the hanging mass since it has the tensions from the ropes. How do I set this problem up? Many thanks!
