Homework Help: Kinematics / Forces Friction Problem?

  1. Sep 14, 2011 #1
    1. The problem statement, all variables and given/known data
    A baseball player slides into third base with an initial speed of 7.00 m/s. If the coefficient of kinetic friction between the player and the ground is 0.37, how far does the player slide before coming to rest?

    2. Relevant equations
    All Kinematics and Forces Equations

    3. The attempt at a solution
    I'm not really sure how to start this problem; there doesn't seem to be enough information given. If the coefficient of friction is given, I feel like I should know what the Normal Force is, but I don't have the mass or the weight of the player, so I'm kind of lost as to how I should start this.

    Call the mass 'm' and continue. Maybe you won't need the actual value. :wink:
