To calculate the amount of work Juanita does, we need to use the formula:

Work = Force x Distance x Cosine(theta)

Where:

Force = 40 newtons (given)

Distance = 32 meters (given)

Cosine(theta) = Cosine of the angle between the direction of the force and the displacement. Since Juanita is pulling the wagon in a straight line, the angle between the force and displacement is 0 degrees, and cosine(0) = 1.

Therefore:

Work = 40 newtons x 32 meters x 1

Work = 1280 joules

Therefore, Juanita does 1280 joules of work.
