Answer
Step 1: Interpret the Motion of the Skateboard from the GraphBased on the description of the graph, we can interpret the motion of the skateboard over time as follows:- Initially, the position of the skateboard increases over time, which indicates that the skateboard is moving forward and accelerating or moving at a constant speed.- Then, the position remains constant for a period, which suggests that the skateboard is not moving; it is at rest.- Finally, the position decreases, which means the skateboard is moving backward towards the starting point or slowing down if it's moving forward.Step 2: Describe the Motion from 0 s to 40 sFrom 0 s to 40 s, the skateboard starts moving forward (or accelerating), then comes to a stop and remains stationary for a while, and finally, it either moves backward or slows down if it's still moving forward.Step 3: Calculate the Average Speed of the SkateboardThe average speed of an object is calculated by dividing the total distance traveled by the total time taken to travel that distance.Given:Total distance traveled = 80 mTotal time taken = 40 sAverage speed (v_avg) = Total distance / Total timev_avg = 80 m / 40 sv_avg = 2 m/sAnswer:The average speed of the skateboard over the 40-second interval is 2 meters per second (2 m/s).
