Problem 7-23 Work - Part 2 - A

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

No. Only a component of $mg$ acts along the plane.
