he following data were obtained for the position of a ball as it rolled along a straight track DISPLACEMENT (CM) 2.90 7.40 11.00 22.70 31.10 TIME 0.60 2.10 3.30 7.20 10.00

dx/dt = 28.2/9.4 = 3 cm/s for the whole trip dx/dt = (11-2.9)/(3.3-.6) = 3 cm/s for part of the trip so I suspect constant velocity of 3 cm/s or 0.03 m/s

@damon is that the answer in my table?

You did not ask any question.
