We measured amount of time, t, it took for a ball dropped from rest to fall a series of increasing heights, y. Acceleration due to gravity, g, was determined from a plot of data.

a) What features of this plot were used to calculate g, and what is the precise mathematical relationship between these plot features and g?

b) How would this experimentallly determined value for g be affected if all of your distance measurements were off by some additive constant? your answer must show using equations or graphs , what the effect will be.

Thanks ahead of time, for the help.
