A light rope is wrapped several times around a large wheel with a radius of 0.450 mm. The wheel rotates on frictionless bearings about a stationary horizontal axis. The free end of the rope is tied to a suitcase with a mass of 19.0 kg. The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.65 m/s when it reaches the ground.   Part A:Calculate the angular velocity of the wheel when the suitcase reaches the ground. Express your answer in radians per second.   Part B:Calculate the moment of inertia of the wheel. Express your answer in kilogram meters squared.
