[问答题]
A person stands on a platform, initially at res 4ytlf ll4cc..t, that can rotate freely wit tn93q s5 gpd9w*m:ba/cl/pt phout friction. The moment of inertia of the personmg s:5l /pna/p9tc9w dq3 btp* plus the platform is $I_P$ The person holds a spinning bicycle wheel with its axis horizontal. The wheel has moment of inertia $I_W$ and angular velocity $\omega_W$ What will be the angular velocity $\omega_W$ of the platform if the person moves the axis of the wheel so that it points (a) vertically upward, (b) at a 60º angle to the vertical, (c) vertically downward? (d) What will $\omega_P$ be if the person reaches up and stops the wheel in part (a)?
