Acarnival 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. the radius of the base of the platform r is 5.5 m. problem 12.051.a - particle kinetics, curvilinear motion, normal and tangential coordinatesdetermine the speed v0 at which the platform a begins to roll upwards. (you must provide an answer before moving on to the next part.) the speed at which the platform a begins to roll upwards is
