Use the position-time graph below to answer the following questions: 4. Describe the motion of the object from 0-2 seconds. Position-Time Graph: - No change in position at first 2 seconds. 5-6 seconds: - Constant positive acceleration. 6-8 seconds: - Constant negative acceleration. 8-9 seconds: - No change in position at first 2 seconds. Time (s) 2 3 4 5 6 7 8 10 11 9-12 seconds: - Constant positive acceleration. 2. What is the total distance traveled? What is the displacement of the object? Total distance traveled: - 6 + 8 + 3 + 2 + 0 + 8 + 0 + 3 = 30 Displacement of the object: - 6 + 8 + 3 - 2 + 0 - 8 + 0 + 3 = 10 6. What is the average speed of the object? What is the average velocity? Average speed of the object: - Total distance traveled / Total time taken = 30 / 12 = 2.5 m/s Average velocity of the object: - Displacement / Total time taken = 10 / 12 = 0.83 m/s

Shown below is a graph of velocity versus time for a moving object The object starts its motion atx = aecunds 1 Figure 1: What is the object $ acceleration att = sec? (Zpt) (b) What t the position of the object att= 15 sec? (3pt) What is the acceleration at t = 2 sec? (Zpt) (d) What Is the distance travelled by the object from [ = 15 sec to t = 3.0 sec and Its positlon the time E27 (Spt) What is the acceleration at t = 40 sec? (Zpt) What Is the fInal position of the objectat t = sec? (3pt) What Is the average velocity of the object In time Interval At from [ = T0 L = 5.0 sec? (3pt)
