Question

2. A parent pulls a toboggan with three children at a constant velocity for 38 m along a horizontal snow-covered trail. The total mass of the children and the toboggan is 66 kg. The force the parent exerts is 58 N [18° above the horizontal]. (a) Draw an FBD of the toboggan, and determine the magnitude of the normal force and the coefficient of kinetic friction. [FN=642N μk=0.086] (b) Determine the work done on the toboggan by kinetic friction. [-2097]] (c) List three forces, or components of forces, that do zero work on the toboggan. [Weight, FN, Fsine] (d) How much work does the parent do on the toboggan in pulling it the first 25 m? [+2097]]
