Answer:
Explanation:
When a position-time graph is curved, it is not possible to calculate the velocity from it's slope. Slope is a property of straight lines only. Such an object doesn't have a velocity because it doesn't have a slope. The words "the" and "a" are underlined here to stress the idea that there is no single velocity under these circumstances. The velocity of such an object must be changing. It's accelerating.
On a position-time graph…
straight segments imply constant velocity
curve segments imply acceleration
an object undergoing constant acceleration traces a portion of a parabola
v = ∆s = 9.5 m = 0.95 m/s
∆t 10.0 s
