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

FBD indicating all forces and directions.

No. Only a component of \(mg\) acts along the plane.
