1. The problem statement, all variables and given/known data A ride at a carnival rotates about a vertical axis. When spinning fast enough the bottom is dropped and the rider sticks to the side. Find the minimum tangential speed so that the rider does not fall. R=radius of circle, u= coefficient of static friction and g represents gravity. The answer must be in these terms. 2. Relevant equations F = ma F = un Ca = v^2/r 3. The attempt at a solution V = sqrt (Ca*r) I think I am missing something here, as it is not with respect to the right variables. Any hints on what to do next, or if I am heading down the wrong path?
