Question

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

Answer 1

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

Answer 2

@damon is that the answer in my table?

Answer 3

You did not ask any question.
