A portion of the recorded data is shown in the figure below.The acceleration of the object at time t = 0.7 s is most nearly equal to which of the following?
a
The slope of the line connecting the origin and the point where the graph crosses the 0.7 s grid line
b
The value of the graph where it crosses the 0.7 s grid line
c
