Explanation:
To keep the rider from sliding down, then the friction force must at least be equal to gravity force
where μ is the coefficient, N is the normal force acted by the rotating cylinder, m is the mass of a person and g = 9.81 m/s2 is the gravitational acceleration.
According to Newton's 3rd and 2nd laws, the normal force would be equal to the centripetal force , which is the product of centripetal acceleration
and object mass m
Therefore
The centripetal acceleration is the ratio of velocity squared and the radius of rotation
Therefore
