Homework Statement
In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will “stick” to the wall and not slide. Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70.
Homework Equations
T = 1/f
and so the people don't slide
(coefficient of friction) (Fn)= mg
( (coefficient of friction)*m*v^2)/ r = mg
The Attempt at a Solution
(coefficient of friction) = (g*r)/ (v^2)
T = (2*pi*r)/ square root of ((g*r)/(coefficient of friction))
and f= 1/T
I got 0.4068 = f
but the program says I am wrong
