To analyze this efficiently, we place ourselves in the non-inertial rotating frame of reference of the cone. In this frame, the block experiences three forces: The gravitational force ( ) acting downward. The normal force ( ) acting perpendicular to the interior surface of the cone. The centrifugal force ( ) acting horizontally outward, where is the radius of the block's circular path. From the geometry of the cone, the radius at a height is given by: r=htanαr equals h tangent alpha
