Physics Work: Solving a problem

The video tutorial explains how to calculate the work done by a tugboat pulling a ship with a constant force of 5000 Newtons over a distance of 3 kilometers. It emphasizes the importance of using consistent units, converting kilometers to meters, and applying the formula for work, which is force times distance. The final calculation results in 1.5 * 10^7 joules, with a brief discussion on expressing this in kilojoules.
