you need to design an industrial turntable that is 48.0 cm in diameter and has a kinetic energy of 0.300 J when turning at 31.0 rpm
i found that inertia of the turntable about the rotation axis
is = 5.71×10^-2 kg m^2
If your workshop makes this turntable in the shape of a uniform solid disk, what must be its mass?
it try to use I=mr^2
so mass = I/r^2
but that don't work
