Answer
A) (graph)
B) Yes, there does appear to be a limiting speed, and because the graph describes a falling object, this may be attributed to air resistance.
Work Step by Step
For part A, we graph the data in the table using time in seconds on the x axis (t) and speed in feet per second on the y axis (S) and then plotting the points. We can see that the graph begins to plateau at around 56 ft/s, indicating that (for part B) there is a limiting speed. Because the problem is describing a falling object, we must think of what could slow the acceleration of a falling object, one possibility is air resistance.
