Ferris wheel: rotation rate for 3g at bottom and seat belt force at top

[luckycharmz]

Cars on a ferris wheel are moving in a vertical circle. The radius of the
wheel in 6 meters. what must be the rotation rate of the wheel in order that riders experience three times their weight at the bottom of the circle? for this rotation rate what will be the required force exerted by the seat belt in the car when the car is at the top of the vertical circle?
