Answer

800 J800 \text{ J}

Step-by-step solution

2 steps

  1. Identify the given values.

    The horizontal force applied is F=20 NF = 20 \text{ N}.
    The distance moved is d=40 md = 40 \text{ m}.

  2. Calculate the work done.

    The formula for work done (WW) when a constant force (FF) is applied over a distance (dd) in the direction of the force is:

    W=F⋅dW = F \cdot d

    Substitute the given values into the formula:

    W=(20 N)(40 m)W = (20 \text{ N})(40 \text{ m}) W=800 JW = 800 \text{ J}

    The work done is 800 J800 \text{ J}.
