6. A 25.6 kg child pulls a 4.81 kg toboggan up a hill inclined at 25.7 degree to the horizontal. The vertical height of the hill is 27.3m. No friction: i) Determine how much work the child must do on the toboggan to pull it at a constant velocity up the hill. ii) Now suppose that the hill is inclined at an angle of 19.6 degree but the vertical height is still 27.3m. What conclusion can you make? (10K)
