A mass `m` is attached to a pulley through a cord as shown in figure. The pulley is a solid disk with radius `R`. The cord does not slip on the disk. The mass is released from rest at a height `h` from the ground and at the instant the mass reaches the ground, the disk is rotating with angular velocity `omega`. Find the mass of the disk.
