Problem 7-23 Work - Part 4 - B
A girl pulls a toboggan of mass \(4.81 \;kg\) up a hill inclined at \(25.7^\circ\) to the horizontal. The vertical height of the hill is \(27.3 \;m\). Neglecting friction between the toboggan and the snow, determine how much work the girl must do on the toboggan to pull it at constant velocity up the hill. [Ans. \(1.29\times 10^3\; J\)]
Accumulated Solution
\(F = mg \sin \theta \\ d = h/ \sin \theta\)
No. The force acts in the direction of \(d\).
