Each problem solution must be formatted like in the textbook and should include: * o List your known information (constants, givens) including the units. * o Write down the equations you plan to use, include the name of the equation if there is one. * o Although, good for error checking, I do not require a step-by-step algebra in which you use to solve the problem(s), but you should provide a guidance for someone to solve the problem after reviewing your solution. * o Highlight your final answer (e.g. a box around it) and don't forget the units.
