A horizontal force of 150 N is used to push a 43.5 kg packing crate a distance of 5.30 m on a rough horizontal surface. If the crate moves at constant speed, find each of the following.

(a) the work done by the 150 N force


(b) the coefficient of kinetic friction between the crate and the surface

  1. (a) 150 N * (distance moved) = 150*5.3 J

    (b) 150 N = M*g*Uk
    Since there is no increase in speed, the two forces balance

    Solve for the coefficient of kinetic friction, Uk
