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?

1 answer

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
