A cord is wound around the rim of the flywheel with a diameter of 60 cm, to the end of which a weight of 2 kg is tied. Determine the moment of inertia J of the flywheel if it, rotating uniformly accelerated under the action of gravity of the load, acquired an angular velocity of 9 rad / s in 3 s.
A detailed solution with a brief note of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
