I demonstrate how to derive velocity from acceleration and how to apply Pythagorean theorem to find speed, particularly when dealing with vectors. I also tackle questions about motion in perpendicular directions and the use of constants of integration. Throughout the examples, I emphasize the importance of careful calculations and understanding the language of the questions to avoid losing marks. Please pay close attention to the methods I use, as they will be crucial for solving similar problems.
