Question

I am working on a Friction lab for my physics class, I will attach my data and graphs.

My experimental coefficient of kinetic friction is 4.375, which gives me a minimum angle (theta) = 77 degrees, which is really far off (experimentally 9.5 degrees).  Have I done something incorrectly?  The data is from my instructor (through a video). 

Thank you.

Theoretically, what is the minimum angle that you can drop the elevated plane to before the block stops sliding? Q6. Test your prediction to find your experimental value. Video (6) At what angle does the block stop sliding? .5 Do a percent error analysis between your theoretical and experimental values. Part 5: Devised an experiment to determine the coefficient of kinetic friction Connect a string to the block and suspend a mass over a pulley so that a block moves up the plane at a constant speed. Draw a free-body diagram and derive an equation for the coefficient of kinetic friction for this case in terms of the suspended mass, the mass of the block, and the angle of incline. (Assume a massless, frictionless pulley)

Part 3: Determining the Coefficient of Kinetic Friction. Now you need to determine the coefficient of kinetic friction. This done by placing the block on the level plane and measuring the force that must be applied to the block to keep it moving at a constant velocity. Again, the force is measured with a spring scale. After each measurement add mass to the block in 100-gram increments. Take 5 force measurements for 5 different block weights. Record your measurements in Table B.
