**1.Homework Statement**

A child pulls a wagon with a constant force of 30 N. How much work is done in moving the wagon 100 m if the handle makes an angle of 30* with the ground?

## Homework Equations

Brown = Vector

W=fd

a

^{2}+b

^{2}=c

^{2}

cosθ= Adjacent/Hypotenuse

sinθ= Opposite/Hypotenuse

tanθ= Opposite/Adjacent

## The Attempt at a Solution

I calculated the force on the x-axis of the triangle since the 100m distance also lies on the x axis.

cos60*=x/30

x=15

I got an answer of 15N for the magnitude of the force and sub this into the work formula along with the 100m distance.

W=fd

W= (15)(100)

W= 1500J

__Geometry and Discrete Mathematics 12__states the answer to be approximately 2600J. The question is #21 on page 58 of the book. What is the correct approach to solve this problem?
