19. An 8.5-kg box is at rest on a flat, frictionless surface. A 170-N pulling force is briefly applied to the box, after which the box moves at a constant velocity of 8.1 m/s in the direction of the pull. For how long was the pulling force acting on the box?

The scientific method and engineering method both essentially arise from one idea, that is tested and finalized. The scientific method calls to use a hypothesis after a question is asked, which essentially develops an idea to continue the process on. The engineering method begins with an issue that needs to be solved, and continues with a step where one generates concepts as a solution to this problem, which is simply put, creating ideas. These both do the same, create ideas to solve an issue/hypothesis. Afterwards, the engineering and scientific method both test that idea, and iterate that till they have created a valid solution. In the scientific method, you test your hypothesis, and try to find the solution to a scientific wonder, similar to the engineering process, where you test a prototype from an idea, and try to find the solution to a practical problem. Their specific steps might be different but their layout/outline is the same, an idea arises, that idea is tested, and that creates something new and helpful.
