Homework Help: Static coefficent

  1. Nov 14, 2007 #1
    A Force 75.0 N is required to set a 25.0kg block into motion and a froce of 60.0N is required to leep it in motion at a constant velocity

    a) The static coefficent of friction is ?
    b) The kinetic coeficent of friction is ?

    Help

    Do you know the equations that are needed to find both that static and kinetic coefficents? You have the initial maximum force and the sliding kinetic force as well as the of the object. These three pieces of information are all you will need to find the two coefficents.
