Circular Motion Problem: An Adventure inside Spinning Cylinders

  1. Feb 10, 2012 #1
    1. The problem statement, all variables and given/known data

    A 60.0 kg person is stuck against the inner wall of a rotating cylinder.
    The radius of the cylinder is 10.0 m and the period is 2.00s. What is the
    minimum coefficient of static friction required to stop him from sliding?


    2. Relevant equations

    Fnet = (4m∏^2R)/T^2



    3. The attempt at a solution

    Tried to understand the problem; could not even. What is the condition for not sliding?

    "What is the condition for not sliding?"
    The frictional force needs to be great enough to cancel the gravitational force.​
