Help with centripetal force

  1. Sep 27, 2007 #1
    Hi can someone help me on this problem.

    a cat dozes around merry go round at radius 5.4 meters. the ride turns on and brought up to turning rate of 7.2 seconds in one complete rotation. how do i find the least static friction coefficient between the cat and the merry go round that will allow the cat to stay in place, without sliding out.

    Compare the centripital force to gravitational force (the ratio).
