Problem 3. On conservation of angular momentum. A person of mass $m$ stands on an edge of a large disk-like platform of mass $M$ and radius $R$. When he starts walking along the edge (in tangential direction) with a constant speed $v$ relative to the platform, the platform starts rotating in the opposite direction. Assume that the platform's rotation about the axle is frictionless. (A) Find the angular speed that the platform acquires with respect to the ground. (B) How will your result in (A) change if the person starts walking from a midpoint between the center and the edge of the platform (in the same direction and with the same speed). (C) How will your result in (A) change if the platform's shape is a ring of the same radius and mass. Assume that the ring is connected to the center of the platform by rods of a negligible mass (just like in a bicycle wheel).
