Question

Graphing either x versus v2 or v2 versus x gives a straight line. In the graph shown above, we chose to plot v2 on the vertical axis and x on the horizontal axis because the theoretical kinematic equation gives the square of speed as a function of distance. From the equation for the line of best fit given, determine the value of μk.

Answer 1

uk isn't defined in the figure or your problem statement, so its not clear what you are trying to find.
