In a carnival they often have a large r = 16 m, cylinder which people stand against the outer wall while it rotates with some velocity v. At a certain point the floor of the cylinder lowers and the people are surprised they don't slide down. The friction between the wall and their clothes is ?s = 0.57.
Part (a) What is the minimum velocity of the cylinder to make someone "stick" to the wall in m/s?
Part (b) What is the frequency f in revolutions per minute of the carnival ride when it has reached the minimum velocity to "stick" someone to the wall?
