The radius of the flywheel shaft R = 10 ^ -2 m. The shaft is wound cord, the end of which is attached a weight of m = 0,2 kg. Under the force of gravity is lowered for the time t = 5s with a height h1 = 1,2 m, followed by the rotation of the wheel by inertia it rises to a height h2 = 0,8 m. Determine the moment of inertia of the wheel.
