Solution must follow the required solution Format. You can find that from the file call “Required Solution Format”. Express your answer to two significant figures and include the appropriate units. A clear translation of the problem is given. Correct assumptions/simplifications are given and related to how they allow the concepts/laws to be used to solve this particular situation. A clearly labeled, correct physical representation is given, with all relevant quantities clearly defined. A complete solution with clear mathematical steps is given, and the answer has correct units. A clear and complete explanation is given for why the result makes sense (or does not make sense if the incorrect answer was reached), and what it tells us about the physics of the situation.
