Which expression represents the total energy of the system at the final time (which is the time when you will determine the velocity of the falling mass)? m is the hanging mass, I is the moment of inertia of the spinning apparatus, w is the angular speed of the rotating apparatus, h, is the final height of the hanging mass, and v is the final speed of the hanging mass. Remember that the hanging mass could still have some potential energy at your final point. O mghy O mu O mu +lu O mgh, + mv O lu + mu + mgh
