A person stands on a platform, initially at rest, that can rotate fmvsdqo2 : t)s.e 4xix*n;on p0rcx8 6/rrthf (s9 3xxwyeely without friction. The moment of inertia of the person plus the plat9 rxcx83(yf sw6/rhtx form 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)?
