against the wall when drops away from the floor. The coefficient of static friction between
person and the wall is u, = 0.35, and the radius of cylinder r = 2m. What is the maximum
(linear) speed necessary to keep person from falling? (g = 9.80)

On the ride "Spindletop" at the amusement park Six Flags Over Texas, people stood against the inner wall of a hollow cylinder with radius 2.9 m and axis vertical. The cylinder started to rotate, and when it reached a constant rotation rate of 0.59 rev/s, the floor on which the people were standing dropped about 0.61 m. The people remained pinned against the wall. What minimum coefficient of static friction is required if a person on the ride is not to slide downward to the new position of the floor?
A car traveling on a flat (unbanked), circular track accelerates uniformly from rest with a tangential acceleration of 1.75 m/s. The car makes it one quarter of the way around the circle before it skids
off the track. From these data, determine the coefficient of static friction between the car and track.

You appear to have forgotten that the static force of friction is also responsible for the tangential acceleration of the car.
