Calculating the Coefficient of Static Friction

  1. Oct 18, 2009 #1
    1. The problem statement, all variables and given/known data

    A 25 kg chair intially at rest on a horizontal floor requires 365 N horizontal force to set it in motion. Once the chair is in motion, a 327 N horizontal force keeps it moving at a constant velocity.

    A: Find the coefficient of Static Friction between the chair and the floor
    B: Find the coefficient of Kinetic Friction between the chair and the florr.


    2. Relevant equations

    I am very new to physics and my teacher has been absent for the entire week. I have no idea where to begin and what equations to use. I really hope that someone out there can help me in my plight.


    3. The attempt at a solution

    Hi Sachin_Sharma, welcome to PF.
    You must have a text book. Now what is the expression for the frictional force?

    Thanks so much! I really should have taken this posting down because I actually did manage to find the answer by using my textbook! I was one step ahead of you, but I nonetheless appreciate your posting rl.bhat.
