Answer:
Step-by-step explanation:
Based on the given hint, it appears that the question is related to the analysis of a physics experiment involving the relationship between velocity, distance, and acceleration due to gravity.
Given that the formula v² = 2ugd is being used, it suggests that the experiment involves dropping an object from a height d and measuring the distance it travels over time, as well as the final velocity it reaches. By plotting the squared velocity (v²) on the vertical axis and distance (d) on the horizontal axis, a straight line can be obtained with a slope of 2ug, where u is the coefficient of friction and g is the acceleration due to gravity.
However, without further information or data from the experiment, it is impossible to determine the specific value of the scale factor used.
