A person stands on a platform, v2:d+p -/atz,*asx htmpfu 5pinitially at rest, that can rotate frey 0l57guuc *bfbuz7m1 ely without friction. The moment uf c *g01lzubbm 7u57yof 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)?
