Need help with my Physics question – I’m studying for my class.

Instructions for Week 5; Part I

Part I:

The student will watch the brief demonstration of the smart-car moving up an incline due to a mass coupled over a pulley. Observe the brief demo carefully and do the following (based on everything you have learned thus far):

1. Draw a force diagram on the smart car. Include all forces you can identify AND their directions. Hint: Draw the appropriate coordinate axis first (see manual and textbook). You may hand-draw neatly or use shapes (the insert-shape method is preferred as you do not have to print anything out and scan to upload).

2. List all of the experimental variables. If they are dependent, what do they depend on?

3. Briefly explain how the work-kinetic energy theorem applies here. What is doing “work” on the smart-car?

Upload as a pdf file (neatly) with all three of these points answered.
