Question
Examine the position vs. time graph of the data and discuss its characteristics (1) Does the graph show the car having a constant velocity t=0.000 s and t= 0.300 s. Why or why not? (2) Does the graph show the car having a constant acceleration between t=0.000s and t=0.300 s. Why or why not? (3) Describe what you think the car is doing at points, A,B,and C on the graph.

(2) Does the graph show the car having a constant acceleration between t=0.000s and t=0.300 s. Why or why not? (3) Describe what you think the car is doing at points, A,B,and C on the graph.Explanation / Answer
a)
no, If it's velocity is constant, the graph must be a stright line.
b)
no, if it's acceleration is constant, the graph must be a parabola, but it is not parabola at point C.
c)
At part A, the car has a positive velocity and it's velocity decreases
At part B, the car is motionless (v=0).
At point C, the car is motionless (v=0), too.
