a person pushes a box across a horizontal surface at a constant speed of .5 meter per second. the box has a mass of 40 kg and the coefficient of sliding friction is .25. The power supplied to the boxx by the person is...

please Explain!!

    Since the box is pulled at a constant speed, the force applied is equal to the force of friction.
    F = F(friction) = ยต*m*g
    Power generated = P = Fv
