Running on Ice

  1. Oct 24, 2009 #1
    1. The problem statement, all variables and given/known data
    A 60.9kg person wishes to run on ice. The coefficient of static friction between his shoes and the ice is 0.123. What is his maximum possible acceleration?


    2. Relevant equations
    Newton's laws of motion



    3. The attempt at a solution
    I figured that Fnet = Ffr, with me then solving for a. This, however, seems almost too easy for the mass cancels out just leaving me with a = (coefficient of static friction)(g). I'm not sure if I need to consider an Fapp force here or not. Is what i'm doing for this question correct, or is there something else i'm missing here? Thanks for the assistance.
