You push a 67 kg box across a floor where the coefficient of kinetic friction is uk = .55. The force you exert is horizontal. (a) How much power is needed to push the box at a speed of .50 m/s? (b) How much work do you do if you push the box for 35 s?

*please list the steps to work out this question.

  • Science-Physics -

    power= force*velocity

    power= .55*67*g*.5 watts

    work= power*time
