A) a horizontal straight line.
B) a vertical straight line.
C) a straight line making an angle with the time axis.
D) a parabolic curve.
E) a hyperbolic curve.

Quizplus · Accepted Answer

Since the object is moving with constant non-zero acceleration in the +x-axis, its velocity will increase linearly with time. Therefore, the velocity versus time graph will be a straight line. The slope of this line (which represents the acceleration) will be positive, since the acceleration is in the +x-axis direction. Thus, the correct choice is C, a straight line making an angle with the time axis. This angle represents the positive slope of the line, which in turn represents the acceleration of the object.
