Question 4

Using the information in the graph, compare the motion of runners A, B, and C. Be sure to compare the initial position and velocity of each runner.

Revolt · Accepted Answer

Runner A starts at the 0 m position and has the highest velocity, represented by the steepest slope. Runner B starts at the 2 m position and has a lower velocity than Runner A. Runner C starts at the 4 m position and has a velocity of zero because the line is horizontal, meaning the runner is stationary. All three runners reach the 4 m mark at 4 seconds.

Question 5

Use the graph to determine the velocity of the object. What is the instantaneous velocity of the object at 3 seconds? m/s What is the average velocity of the object? m/s
