A carnival ride is designed to allow the general public to experience high acceleration motion. The ride rotates about Point O in a horizontal circle such that the rider has a speed v0. The rider reclines on a platform A which rides on rollers such that friction is negligible. A mechanical stop prevents the platform from rolling down the incline. Determine
(a) The speed v0 at which the platform A begins to roll upwards,
(b) The normal force experienced by an 80-kg rider at this speed. |
