At a constant velocity, you are pulling a 10kg object with. Force P. How much work is done by P to move 87cm? Assume kinetic frictional coefficient = 0.26.
constant velocity means............ applied force=frictional force=p=kinetic friction coefficient*mg=0.26*10*9.8=? now we know .... work=force*distance=0.26*10*9.8*0.87joule plz feel free to ask if u hv any confusion!!
