A cylindrical carnival ride is spinning with a frequency of 0.5 Hz in a circle of radius 3 m which allows a 60 kg person to “stick” to the side of the ride as it spins.
T = 2s v = 9.42 m/s
A) Find the normal force exerted on the person.
B) What minimum µs is necessary between the rider and the wall for the rider to stick to the wall?

A)The normal force exerted by the cylinder must equal the centripetal force, M v^2/R
B) The static coefficient of friction. µs, must be large enough so that
µs*M v^2/R >or= M g
µs >or= g*R/v^2
