Work done by movers

  1. Nov 13, 2009 #1
    How much work did the movers do (horizontally) pushing a 160-kg crate 10.3 m across a rough floor without acceleration, if the effect coefficient of friction was 0.50?

    I don't know an equation that matches up with the given info, could someone get me started?

    It involves work and friction. Do you have formulas for those concepts?

    Well the only formula on my formula sheet for class involving friction is Ffriction=u times N and I don't even know what that means...: /
