(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

Centripetal Force= (mv^2)/r

Force of friction=(mu)(mg)

Velocity=(r)(ω)

3. 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?
