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.

Why is it necessary to convert kilometers to meters in this problem?

What is the final answer for the work done by the tugboat in joules?
