In a "Rotor-ride" at a carnival, people are rotated in a cylindrically walled "room." (See Fig. 5-35.) The room radius is 5.4 m, and the rotation frequency is 0.8 revolutions per second when the floor drops out.

What is the minimum coefficient of static friction so the people will not slip down?

• physics -

friction=mg
mu*mv^2/r=mg

mu*w^2 r= g
solve for mu
