  1. To calculate the total distance and total displacement, we would need the specific distances for each segment of the runner's path from B to A, A to D, and D to C. As this information wasn't provided, we cannot determine the exact values. However, the total distance would be the sum of all individual segments, while the total displacement would be the straight line distance from the starting point (Point B) to the endpoint (Point C) measured in a specific direction (indicating that displacement could be denoted in meters East or another direction).

  2. The average speed is calculated as the total distance divided by the total time. Average speed = Total distance / Total time = 10 meters / 5 seconds = 2.0 m/s. So the answer is: c. 2.0 m/s

  3. Without a specific graph reference for the remote-controlled car, it can be inferred that if the speed is constant, it would either be traveling at 6 m/s or 12 m/s. If there is no change in speed (moving at a steady pace), the answer would be: b. It is traveling at a constant speed of 6 meters per second. (Assuming this option fits the graph context).

  4. When balanced forces act on an object, the net force that results is: b. equal to zero.
