Aposition-time graph is shown below: a speed versus time graph is shown with y-axis labeled speed in centimeters per second up to 15 and x-axis labeled time in seconds up to 10. a straight line connects the points 0, 0 and 3, 3. a horizontal line connects points 3, 3 and 6, 3. a straight line connects 6, 3 and 10, 11. which statement accurately describes the motion of the object in the graph above over 10 seconds? the object moves forward at 1 cm/s, stops, and then continues at the same velocity. the object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s. the object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s. the object is at rest for 3 seconds and then decreases velocity to 1 cm/s for 3 seconds.
