A 5 kg spinning ring of inner radius 30cm and outer radius 40cm is dropped on a flat disk, where it interlocks and causes the disk to spin. Before the ring was dropped, it was spinning at 60 Hz. If the disk has a mass of 2kg and a radius of 1 meter, how much force needs to be applied to the rim of the disk (at a 90 degree angle) to bring it to a stop in 5 seconds
