Question
The rotor is an amusement park ride where people stand againstthe inside of a cylinder. Once the cylinder is spinning fastenough, the floor drops out. a) What force keeps the people from falling out the bottom ofthe cylinder? b) If the coefficient of friction is 0.40 and the cylinder hasa radius of 2.5 m, what is the minimum angular speed of thecylinder so that the people don't fall out? (Normally the operatorruns it considerably faster as a safety measure.) The rotor is an amusement park ride where people stand againstthe inside of a cylinder.

r=rg/s
now angularspeed==g/rs=9.8/2.5*0.40=3.130rad/sec
