Homework Help: Coefficient of friction between puck and ice

  1. Jun 13, 2017 #1
    1. The problem statement, all variables and given/known data

    A hockey puck travels across the ice at 6.5m/s. the puck travels a total of 7.6m. What is the coefficient of friction between the puck and the ice.

    2. Relevant equations

    Ffr= coefficient of friction x force normal

    3. The attempt at a solution

    I found my acceleration, but I feel like I cannot get the coefficient of friction without the mass. Please help.

    It can be done with the 2 equations you gave. Just substitute everything you know and see if anything cancels.

    What is the normal force equal to, in this situation?
