ow much work did a horse do that pulled a 200 kg wagon 80 km along a level road if
the effective coefficient of friction was 0.060?
I used W=Fd to find the work (W=1960*80000=156800000) then I got the force of friction by ff=(coeff)Fn and got (.06)*1960=117.6. I then got the W(friction)=117.6(80000)=-9408000 and by subtracting the 2 Work answers I got 14739200J
