A man standing on a fixed platform axis in the form of a disk, rotating light-handed vertical axis of the wheel radius of 40 cm and a weight of 4 kg, distributed on the rim of the wheel. The total moment of inertia of a person with a platform 8 kg * m2. human inertia wheel Center lies on the axis of the platform. Wheel axis forming an angle of 30 ° with the axis of the platform, it has led people to rotate. Determine the speed of the platform with a person if the wheel spins the power cord tension 500 N force at the rim tangentially within 1.5 seconds.
