A pulley in the form of a uniform disk has a rope hanging over it.The circumference of the pullet is 1.2m and the pulley's mass is2.2 kg. The rope is 8m long and has a mass of 4.8 kg. When the difference in heights between the two end of the rope is 0.6m the system is at rest.

1- What is the angular Speed of the pulley when the difference in height between the two ends of the rope is7.2m?
2- Obtain an expression for the angular momentum of the systemas a function of time while neither end of the rope is above the center of the pulley. (There is no slippage between the rope andthe wheel)
