A 60.0-kg person is standing on the west edge of a horizontal circular game that has a moment of inertia of 500 kg · m² and a radius of 2.00 m. the game is initially idle and it is free to turn around a vertical axis without friction through its center. After the person begins to walk around the edge in a clockwise direction (viewed from above the system) with a constant speed of 1.50 m / s relative to the Earth. a) Consider the person-game system while the movement begins. Does the mechanical energy of the system is preserved? Is the momentum of the system conserved? The amount of movement angular system is conserved? b) In what direction and with what angular speed does the game? c) How much chemical energy does the person's body convert into mechanical energy as the person gets himself and the turntable in motion?
