Homework Help: Circular Motion

  1. Jun 29, 2010 #1
    The coefficient of friction between a certain brass block and a large revolving turntable is µ = 0.17. How far from the axis of rotation can the block be placed before it slides off the turntable if it is rotating at 33 1/3 rev/min?

    i was wondering was this the equation to solve this question?
    m ω^2 R <= µ m g

    R <= µ g / ω^2



    3. The attempt at a solution
    1. The problem statement, all variables and given/known data



    2. Relevant equations
