If you use a horizontal force of 30.0 N to slide a 11.5 kg wooden crate across a floor at a constant velocity, what is the coefficient of kinetic friction between the crate and the floor? how i do this?

  • physics -

    pushing force-frictionforce=ma=0
    30-mg*mu=0
    solve for mu.

  • physics -

    yes
