Bicycle Distance

  1. Oct 10, 2016 #1
    1. The problem statement, all variables and given/known data
    A girl is heading home riding her bike she notices a giant wooden log is blocking the road 42m away. If the friction coefficient between her bike tires and the road is 0.36 and she is driving at 25km/h,then what is the distance required for her to stop given that the total mass of the girl and the bike is 95

    2. Relevant equations
    Kinematics and friction coefficient

    3. The attempt at a solution
    Am totally lost should I find Fk and then find the acceleration and make it negative?
