A very light rope is wrapped around a wheel of radius r = 2.0 meters and does not slip. the wheel is mounted with frictionless bearings on an axle through its center. A block of mass 14 kg is suspended from the end of the rope. When the system is released from rest, it is observed that the block descends 10 meters in 2.0 seconds. What is the moment of inertia of the wheel?
