A speed versus time graph is shown:
A Speed versus Time graph is shown with y-axis labeled position in centimeters per second up to 5 and x-axis labeled time in seconds up to 8. A straight line connects the points 0, 0 and 4, 4. A horizontal line connects points 4, 4 and 8, 4.
Which statement accurately describes the motion of the object in the graph above?
Group of answer choices
