In an amusement park ride, people are spun at 5 radians per sec in a 3 m cylinder. What is the coefficient of friction to prevent people from falling down?
Centripetal Force= (mv^2)/r
Force of friction=(mu)(mg)
The Attempt at a Solution
V=(3 m)(5 rad/sec)=15 m/s
Centripetal force=force of friction...
