A father pulls his young daughter on a sled with a constant velocity on a level surface a distance of 10 m, as illustrated in Fig. 5.27a. If the total mass of the sled and the girl is 35 kg and the coefficient of kinetic friction between the sled runners and the snow is 0.20, how much work does the father do?
