A collar B, of mass m and negligible dimensions, is attached to the rim of a hoop

Question:

A collar B, of mass m and negligible dimensions, is attached to the rim of a hoop of the same mass m and of radius r that rolls without sliding on a horizontal surface. Determine the angular velocity ω1 of the hoop in terms of g and r when B is directly above the center A, knowing that the angular velocity of the hoop is 4ω1 when B is directly below A.
