A 24.5 kg child pulls a 3.75 kg toboggan up a hill inclined at 25.7° to the horizontal. The vertical height of the hill is 30.3 m. Friction is negligible. (a) Determine how much work the child must do on the toboggan to pull it at a constant velocity up the hill. (b) Now suppose that the hill is inclined at an angle of 19.6° but the vertical height is still 30.3 m. What conclusion can you make?
