A 25 kg chain initially at rest on a horizontal floor requires a 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 chain and floor.

b. Find the coefficient of kinetic friction between the chair and the floor.

I have a lot of problems like these but I just need to know how to do one to figure them all out, thanks in advance.

  • Physics -

    friction force=365N if in constant velocity
    mu*m*g=365 solve for mu

    mu=m*g=327 solve for mu.

  • Physics -

    The static friction is 1.5
    The kinetic friction is 1.3
