This document provides step-by-step instructions for solving collinear dynamics problems using Newton's Second Law. It works through an example problem of determining the acceleration of a water skier being pulled by a rope with an opposing friction force. The 10 steps include drawing the system, labeling knowns, identifying the unknown, drawing motion and free body diagrams, writing the components of Newton's Second Law, substituting known forces, plugging into the equations, solving, and including units in the answer. The document emphasizes showing all work and provides additional example problems and questions from students.
