1.44. The disk-shaped plate rotates by inertia about a vertical axis with frequency n_1 = 14 〖min〗 ^ (-1). At the edge of the platform is a man. When the person moved to the center of the platform, the frequency increased to n_2 = 25 〖min〗 ^ (- 1). Weight of the person m = 70 kg. Determine the mass of the platform. The moment of man´s inertia is calculated as for a material point.
