## Homework Statement

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?

## Homework Equations

Centripetal Force= (mv^2)/r

Force of friction=(mu)(mg)

Velocity=(r)(ω)

## The Attempt at a Solution

V=(3 m)(5 rad/sec)=15 m/s

Centripetal Force=(M(15^2))/3=75M

Centripetal force=force of friction...

75M=9.8(mu)M

75/9.8=(mu)=7.653?
