How Much Work Is Done Pulling a Wagon at an Angle?

[Valenti]

Homework Statement

Kids are pulled 2km around a town in a wagon,The handle of the wagon is on an angle of 30 degrees from horizontal and requires 200N to maintain constant velocity. Determine the amount of work done against non‐conservative forces on this walk.

Δx = 2km = 2000m
angle θ = 30
Fapp = 200N

Homework Equations

W= fΔx(cosθ)

The Attempt at a Solution

W= 200(2000)(cos30)
=346410 J
=346 KJ

Hi Valenti, Welcome to Physics Forums.

Your calculation looks fine.

Please note that thread titles should reflect the nature of the problem and the area of physics involved. "Homework check" doesn't do that. I've changed your thread title to "Work done pulling a wagon" to be more descriptive of the content.
