7) A parent pulls a toboggan with three children at a constant velocity for 38 m along a horizontal snow-covered trail. The tota children and the toboggan is 66 kg. The force the parent exerts is 58 N [18 above the horizontal]. 1. Draw an FBD of the toboggan, and determine the magnitude of the normal force and the coefficient of kinetic friction. 2 Determine the work done on the toboggan by kinetic friction. 3. list three forces, or components of forces, that do zero work on the toboggan. 4. How much work does the parent do on the toboggan in pulling it the first 25 m
