Physics Question

  1. May 26, 2008 #1
    I'm doing a review for my physics final, and it's asking me to find the coefficient. The problem says,

    A brick has a mass of 1,2 kilograms. A force of 5.4 N is required to move the brick across the floor with a constant velocity. What is the coefficient of friction?

    What is the equation I use to solve this?

    Try and use Newton's Second Law.

    I'm assuming this is coefficient of kinetic friction?

    coefficient = Friction force / Normal force


    And when you move at constant velocity, total forces on said object = 0, so can you figure it out from there?
