A person stands on a plat, wr, an iimf):*sni*hform, .t5d z +s yarz0 ;++5mihwaaininitially at rest, that can rotate freely without friction. The moment ayrz.m5+i;d +a z+ 0aisth5nwof inertia of the person 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)?
