Homework Help: Kinetic Friction of hockey puck

  1. Jan 14, 2010 #1
    1. The problem statement, all variables and given/known data

    In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 1.71 m/s. However, this speed is inadequate to compensate for the kinetic friction that exists between the puck and the ice. As a result, the puck travels only one-half the distance between the players before sliding to a halt. What minimum initial speed should the puck have been given so that it just reached the teammate? Assume the force of kinetic friction is the same on the puck everywhere between the two players. Also assume the ice surface is flat and μk = 0.1.

    2. Relevant equations

    3. The attempt at a solution

    Have you even tried doing this problem?

    Can you set up the necessary equations? Do you want to do this from an energy or force perspective? Either way works.
