A graph showing motion of an object is plotted with the velocity on the vertical axis and the time on the horizontal axis. The graph is a straight line. Which of these quantities CANNOT be determined from this graph?
A) The displacement from time t = 0.
B) The initial velocity at t = 0.
C) The acceleration of the object.
D) The average velocity of the object.
E) The initial position of the object.

The graph only gives information about the object's velocity and time, so the initial position or displacement cannot be determined without additional information. The other quantities can be determined from the graph, for example, the initial velocity can be found from the y-intercept and the acceleration can be found from the slope of the line.
