REQUIRED FORMAT FOR HOMEWORK

HOMEWORK MUST BE NEATLY PRESENTED

1. Write only on one side of the paper. 2. Begin each problem at the top of a new page. 3. Copy the problem statement from the text at the top of your page. 4. List all known quantities including their values and units. 5. Draw a simple sketch to illustrate the problem. 6. List all assumptions including those given and those you make. 7. Write all your equations and calculations neatly. 8. Box all important answers.

IF YOUR HOMEWORK DOES NOT FOLLOW THIS FORMAT IT WILL NOT BE GRADED.
