Homework Help: Coefficient of kinetic friction of a hockey puck

  1. Feb 9, 2010 #1
    A hockey puck on a frozen pond is given an initial speed of 20.0 m/s. If the puck always
    remains on the ice and slides 115 min before coming to rest, determine the coefficient of
    kinetic friction between the puck and ice.

    Welcome to PF,

    Just use the initial velocity and deceleration time to figure out what the acceleration must have been.

    From Newton's Second Law, you can use the acceleration to determine the net force. Of course, there is an unknown (mass of puck) but it should not be required in the end.

    EDIT: PLEASE use the homework help posting template (the one you deleted) in the future, and show your work! We need to see at least what attempts you've made on the problem.
