A. 38.0 \( \mathrm{kg} \) box initially at rest is pushed \( 5.10 \mathrm{~m} \) along a rough, harizontal floor with a constant applled horizontal force of ths \( w \). If the coefficiont of friction between box and floof is D.300, find the faltowing. (a) the work done by the appled force 1 (b) the increase in internat energy in the box-floor system due to friction (c) the workidone by the normal force (d) tibe wark done ty the gravitational force (e) the chanae in kinetic eneroy of the bax (1) the final soeed of the boxi
