The diagram shows the speed-time graph of an object. Speed m/s 18 6. Time/s 10 13 a) Find the acceleration of the object when t = 8.

Two robots in a factory move on parallel straight tracks. The two tracks are right next to each other. Engineers tested the robot control system. The graph shows the velocities, in meters per minute, of the robots A and B (functions are named for the robots) during the 10-minute test. The sign in the velocity values corresponds to direction: positive is right, negative is left. Use the graph to answer the following questions about the system test. a. How far and in what direction from the starting position is robot A after 6 minutes? Velocity 4- 10 b. How far and in what direction from the starting position is robot B at the end of the 10-minute test? What is the distance this robot travels during the 10-minute test? -4 c. Use the graph to evaluate the integral B(t) dt. Describe in words, and using the value you found, what this says about the corresponding robot.
