Its acceleration over 30 seconds is shown in the graph below: (2 points) 5 - 100% + 1 Position vs. Time Acceleration vs. Time Position (cm) Time (s) > 10s 254 Time (s) 3. (02.09 MC) Which statement accurately describes the speed of the object in the graph above over the four seconds? Use the graph above to determine the change in speed of the object between 20 and 30 seconds? A position-time graph is shown below: (2 points) Speed is increasing. 6 m/s Speed is constant. 1 15 Position vs. Time 30 m/'s 10 Speed is decreasing. 60 m/s Position (cm) O Object is at rest. 180 m/s W 4 (02.09 MC) Time (seconds) 2. (02.09 MC) A velocity-time graph is shown below: (2 points) Which statement accurately describes the motion of the object in the graph above over 10 A speed-time graph is shown below: (2 points) Velocity vs. Time The object moves forward at 1 cm/s, stops, and then continues at the same velocity. 25 20 B The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/S. Speed vs. Time 15 Velocity (mis) The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/S. 10 Speed (cm/s) The object is at rest for 3 seconds and then decreases velocity to 1 cm/s for 3 seconds. Time (seconds) Time (seconds) What is the average acceleration of the object represented in the graph above over the 10 seconds? h How far did the object travel by the end of eight seconds, according to the graph above? Oom/s It traveled 12 centimeters. O 2 m/s2 It traveled 16 centimeters. O 4 m/s2 It traveled 24 centimeters. O 6 m/s? It traveled 32 centimeters
