The cart rolls down the ramp and hits a spring. The angle of the ramp is varied and the
maximum spring compression is recorded for each angle. The data is presented below. What
is the spring constant?
the file included the question, professor need us to find the coefficient of friction, and find
uncertainty in the spring constant, and also evaluate some data that is deviated from the fitted linear
line.
professor said, "the intercept primarily gives you the coefficient of friction."
I dont know what he means
he also said, "If you include friction and use the small angle approximation, you should find that
x^2(6) is a linear function. The intercept is determined (in part) by the coefficient of friction. The
slope is determined (in part) by the spring constant but the friction has no impact on the slope."
please show me that procedure in the answer
