They repeat the experiment 10 times. From the videotape, they measure the distance and calculate the velocities and accelerations with time. They average the values and plot them on graphs. 150 100 50 0 0 2 4 6 Time (s) Distance (m) 50 40 30 20 10 0 0 2 4 6 Time (s) Velocity (m/s) 15 10 5 0 0 2 4 6 Time (s) Acceleration (m/s/s) What is one way to simplify the description of the results of this experiment?
