OPENING QUESTION:
1) An object of unknown mass but known composition is placed on a ramp, also of known composition. Derive an equation that will allow you to determine the coefficient of static friction (μs) between the object and the ramp using only the angle of the ramp.
You must include the derivation in your lab and it must be fully typed, no handwritten items at all.
2) A block of wood of known mass is placed on a surface. A string is connected to that mass and run over a pulley to a mass (or masses) such that the object slides at a constant rate.
Work with your team to ellaborate on why that setup is so key to finding the coefficient of static friction (μk)
Now derrive an equation to calculate the value of (μs) using known values.
This derivation must also be included in your lab, fully typed. There is no reason whatsoever to include hand written items.

I asked you on Monday to work with your team to determine the feasibility (workability) of creating a meaningful graph that shows both the coefficient of static friction and the coefficient of kinetic friction.
Remember, the goal here isn't simply to create a graph, the goal here is determine if there is any meaningful data to be determined by doing that.
That's a tough one.
Let's discuss.
