A cat dozes on a stationary merry-go-round, at a radius of 6.9 m from the center of the ride. The operator turns on the ride and brings it up to its proper turning rate of one complete rotation every 7.3 s. What is the least coefficient of static friction between the cat and the merry-go-round that will allow the cat to stay in place?

centripetal force= friction force m*w^2 r= mu*mg w=2PI/period= 2PI/7.3 rad/sec solve for mu.
