Friction lab

Complete all parts of the friction lab (A-C).
Some things to watch out for in particular are:
Your lab report should be neat and easy to read.
Provide written descriptions of values and calculations.
Data table should have descriptive titles.
All values, and and data tables in the spreadsheet should have labels, and units.
Make sure all values have appropriate units.
Make sure you have correct significant figures.
Make sure your final values are correct. Watch out for rounding errors that occur when you round intermediate results too much. Normally I keep an extra significant figure in intermediate results.
