Quizplus · Accepted Answer

The work done is calculated using the formula: Work = Force × Distance × cos(θ). Here, the force is 1300 N, the distance is 4 km (or 4000 meters), and θ is 25 degrees. Converting the angle to radians and calculating gives: Work = 1300 × 4000 × cos(25°) = 4,712,800 N-m or 4,712.80 km-N.
