Homework Statement
A boy does 465 J of work pulling an empty wagon along level ground with a force of 111 N [31° below the horizontal]. A frictional force of 155 N opposes the motion and is actually slowing the wagon down from an initial high velocity. The distance the wagon travels is _____.
Homework Equations
W = Fdcosθ
The Attempt at a Solution
465 J = (111 N)d(cos31°)
d = (465 J)/(111 N)(cos31°)
d = 4.89 m
Where does the frictional force come in here? Does it actually affect the distance traveled or does it just slow down the wagon?
