A light rope is wrapped several times around a large wheel with a radius of 0.435 m. The wheel rotates in frictionless bearings about a stationary horizontal axis. The free end of the rope is tied to a suitcase with a mass of 18.0 kg. The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.60 m/s when it reaches the ground.
(a) the angular velocity of the wheel when the suitcase reaches the ground
my correct anwser is 8.28 rad/s
(b) the moment of inertia of the wheel.
