Velocity vs. Time B Velocity vs. Time B Velocity (mis) > Velocity (mis) 10 Time (seconds) c 10 Time (seconds) Was the object accelerating during the time interval labeled OBJ? (5 points) What was the acceleration during the segment labeled "A"? (5 points) Yes 4 m/s/s No 5 m/s/s Q 10. Match the terms with their definitions. (4 points) 10 m/s/s 1. Average speed a. Speed at a particular instant of time 20 m/s/s * 2. Acceleration b. Total distance covered divided by the total time required c. Rate of change of velocity with time 3. Speed d. Rate of change of distance with time Position vs. Time 4. Instantaneous speed Postion (meters) ) Position vs. Time Q Q 19. 0 Time (second] The graph shows the motion of an object traveling in a straight line as a function of time. What is the average speed of the object during the first two seconds? (5 points) Position (milesk O sm/'s 20- 2.5 m/'s O 10 m/'s Q 16. Time hours) O 20 m/'s Study the graph shown. It is a graphic of a car trip taken by Karen and her mother. The starting position (0.0) is their home. Calculate the average speed of the car during the first hour of the trip. Show your work.
