www.freelance-teacher.com PROJECTILE MOTION PROBLEMS Problems document Brief answers to these problems are available in the Answers document. Full solutions to the problems are available in the Solutions document, and in the YouTube videos. You can find links to these resources at my website: http://www.freelance-teacher.com/videos.html Links to the documents are also in the video description boxes for the YouTube videos. You can support these resources with a monthly pledge of $1 (or more) at my Patreon page: http://www.patreon.com/freelanceteacher This video series is intended for students who find this material to be difficult, so in the videos I proceed slowly and repeat myself a lot. If you find the videos to move too slowly, you can simply try the problems in this Problems document, study the solutions in the Solutions document, and skip to any particular parts of the videos that cover aspects of the solutions that you find confusing. Advice for those who find this material to be difficult: You should complete the problems in order. Take your time. As a beginner, your goal is to learn how to get the problems right—not, for the time being, how to get the problems right fast. Don’t “wing it”. Try to use the same systematic process and notation in your solutions as I use in this Solutions document and in the video solutions. Model your scratchwork on the scratchwork illustrated in these Solutions and in the videos. Make your scratchwork as neat and clean as possible. Don’t work in pen. Use a pencil with a good eraser. Always include a sketch in your solution. Make your sketch as neat as possible, and as big as space will allow. When possible, build the question and givens into your sketch. When possible, keep updating the sketch throughout your solution with new information that you figure out in the course of your solution. If you don’t know how to solve a problem or get a problem wrong, then, after reviewing the solution, you should retry the problem, before moving on to the next problem in the series. Keep redoing each problem until you can get it right. Try to avoid careless mistakes. Double check each line you write down in your solution before you write down the next line of your solution. Your goal is to learn how get full credit on each problem. Don’t settle for partial credit—avoid careless mistakes! Print out the Problems document. Read the problem carefully at least twice before beginning to work on the problem. Reread the problem periodically while you are solving the problem to check for details you may have missed or forgotten. Check the problem one more time when writing your final answer to be sure you answered the right question and answered all parts of the question.
