Flywheels are solid, uniform disks that spin around an axis running through their center of mass and perpendicular to the plane of the disk. They are integral parts of many mechanical devices. One such flywheel spinning at 500.0 rpm has a radius of 1.2 m and requires 5.1 kJ of work in order to bring it to rest. What is the mass of this flywheel? Inywheel = MR2/2 %3D
