Draw a model along side the calculations and answer the following questions.

Activity: Friction Objective: Calculate the coefficients of friction (static and kinetic) between an inclined plane and a block of wood. Materials List: inclined plane, pulley, protractor, friction sled, string, masses, ring stand Procedures: 1. Brainstorm with your group to develop a protocol (set of procedures) to accomplish the Objective. 2. List the materials you will need to accomplish your protocol. 3. Draw the equipment set-up. + List all the forces that act on the sled. Draw the Free Body Diagram (FBD) and label each force. 5. Test your equation in #4 for ms = (sled+100g), mn - 200g and IA = 27 degrees wrt horizontal. a. Calculate u using the equation from #4. Set up the ramp and test. Conclusions : 1. What is the mathematical relationship between u, ms, mh, and incline angle (IA)? Show your work. 2. How do you know your predicted values are correct
