Answer #1

Assuming that the question reads "How FAR did he push the cart"

Work done is displacement multiplied by that component of force which is in the same direction as the displacement.

Here the angle between force and displacement is . The component of force in the direction of displacement will be

Let the displacement of the cart be .

Then,

Here,

He pushed the cart a distance of 17.6 meters.
