Work is calculated by multiplying the force exerted with the distance covered by the object. The force and the displacement should be parallel. In this item, we have to calculate first the horizontal component of force.

x-component of force = (26 lbs) (cos 30°)

= 22.52 lbs

Multiplying the calculated value by the displacement of 90 ft will give us the final answer of 2026.50 lb. ft.
