Question

The carnival ride from Prob 12.51 is modified so that the 80-kg riders can move up and down the inclined wall as the speed of the ride increases. Knowing that the coefficient of static friction between the wall and the platform is 0.2, determine the range of values of the constant speed v0 for which the platform will remain at h = 1.5 m.
Reference to Problem 12.51:

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 vo. 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 vo at which the platform A begins
to roll upward, (b) the normal force experienced by an 80-kg rider
at this speed.
